ProBook series was always hit-n-miss in terms of docking; some had it, some didn't. 4525s is a 2010 model. Whereas even today you can find modern ProBooks with docking support (some with proprietary ports, some with USB-C/TBT only). I don't think it's correct to say that there was any trend towards removal of docking ports in this model line.
If anything, it's true that there is a trend towards replacing bottom-mounted docking ports for side-mounted ones, again, in order to support slimmer chassis. HP was one of the first with this approach (maybe the first, don't know). Lenovo recently followed suit (with **80 line). As a bonus point - now the same mechanical docks can also be used for X1 Carbon series, which previously was limited to USB-C/TBT only).

That's a good point. I only used my USB-C dock with laptops running Win10, which has all the drivers built-in already, but I can imagine drivers being a problem for old Windows, Linux or pre-boot, as you noticed.
