Why are they so rare?
- very heavy & bulky, so don't fit many 'laptop' use cases
- very expensive compared to desktops with similar specs
I have to disagree with you here because with most recent (2020 onwards) 17" laptops, this is simply not the case.

Some 17's may be on the bulky side, but current performance 17" gaming machines like the Asus ROG Strix and Lenovo Legion series are actually rather compact considering the display size. As for weight, that depends more on the size of the battery and the quality of the cooling system, as these two components are the heavyest components of a laptop.
A good example here are the Asus TUF A15 FA506IV - a mid-end 15.6" machine and it's 17" counterpart, the A17 FA706IV. They come in several configurations (60wh or 90wh battery, with or without a SATA drive bay) but are both configured with a Ryzen 4800 and an RTX 2060. Personally, I've owned the 15" FA506, but had the chance to play around with the 17" version, the FA706, and I have to say, apart from the size, the weight is about the same. Both machines were configured with the large 90wh battery and no SATA drive bay, both had the ryzen 4800h and the RTX 2060. I was expecting the 17" model to have better cooling, but it did not. In fact, taking apart the 17" model revealed the exact same (mediocre) heatpipes, with the only difference being the fact that the 17" model used slightly longer heatpipes for the GPU side of the cooler so as to fit the larger case. The motherboards look the same between the two laptops, with on-motherboard ports mounted to the left side of the case, and a ribbon cable + extra PCB for the I/O on the right. Because of this the only difference I can spot between the 17 and 15" versions is the length of said ribbon cable.
I currently use a 17" Asus Strix Advantage G713QY witch I bought in autumn 2021 and I've been lugging that around whenever I need to. It is heavyer then my old FA506, but not by much, and it's rather compact for a 17" machine. For me at least, the extra bit of bulk is offset by the larger screen. The laptop will fit in most backpacks, including most designed for a 16" laptop.
Older machines are another story tough... In 2015 I owned a laptop I remember fondly - a 17" ROG G751JY which was a bulky boy. Because of the cooling system's design, it would only fit into some backpacks, those designed for large 17" gaming machines. It was also quite heavy - both the laptop itself and the power brick. Said power brick needed to come with because unlike my Strix G713 which gets up to 8-8.5h of battery, meaning I can leave my power brick at home most of the time, the G751 could only manage 3-3.5h at best.

Again, I have to disagree. In 2015 I payed around 1100 euro for the GTX980M (equivalent to the desktop GTX970) equipped G751. A well made custom built desktop (4th gen i7, 8gb of ram, GTX 970) with a similar configuration cost about as much, more if you add in peripherals. On the other hand, you do get better performance out of a desktop due to higher TDP parts and much much better cooling. Not to mention nvidia and AMD misleadingly name their mobile GPUs - two examples being the GTX 980M, witch has the exact same core count and memory configuration as the desktop GTX 970, or the AMD Radeon 6800M, witch is in fact a binned RX 6700M, but I did take these factors into account when considering what to buy.
Things took a turn for the worse during the pandemic and mining boom. The FA506IV I owned in that period cost me about as much as A SINGLE DESKTOP RTX 2060!!! Prices for GPUs were so bad that buying a laptop was cheaper than buying a GPU alone.... Same story with my G713QY, which comes with am RX 6800M. Back when I got the laptop I payed around 1500 euro for it, while the equivalent graphics card (the desktop RX 6700M) was either out of stock or cost in excess of 1400 euro in my country.
And yes, the FA506 is a 15" laptop, but the 17" version I wanted was never in stock, apart from the 60wh battery + RTX 2060 or 90wh + GTX 1660 versions neither of which interested me as I wanted the big battery + big GPU.

- still a small screen and crappy keyboard connected together for poor ergonomics
^^^ This. So much this. ^^^ Regardless of how large the laptop is, I still find the ergonomics terrible. The screen is too small and way to low. I used to work on my 15" FA506 with an external monitor and keyboard when at home, and if I needed to do any prolonged work on it in the field, I'd always get terrible neck cramps and eye strain. To mitigate this, I began carrying around a compact wireless keyboard and would put the laptop on top of whatever objects I could find (books, boxes, whatever I could put on a desk to raise the screen to eye level) just so I could work on the bloody thing for more than 30mins - that would aliviate hand and neck issues, but the eye strain is still there.
WITCH IS WHY I OPTED FOR A 17" LAPTOP.
The 17" versions are a bit easier on my eyes, but again, in the field I use whatever I can to raise the machine to eye level, since the 17" screen despite being more comfortable is still insufficient for ergonomics.
