That is exactly how these things go. It's happened to me a few times that I buy something, then run into that same thing days, weeks, or a month or two later. I will often find a use for both, and it never hurts to have spares of stuff this old, so I look at it as "plentiful" rather than "redundant".

The StarTech one is d/c'd now, and unfortunately, the Athena Power one looks like trash. Do you know of another retail AT supply? (Serious question.) My builds are either personally refurbished AT supplies, or ATX with the adapter cable. I have my reservations that you'll be able to produce something more convenient and less expensive than the common ATX-to-AT adapter cable (with optional inline regulator). If you can, great! But, maybe don't get too invested in that idea until you run some numbers. 🤑 It's hard to beat commodity parts - it's either driven 100% by cost (which you can almost never compete with), or features... which in this case, is either a simple adapter that already exists, or calls for some degree of customization that will differ for everyone.
I still want to see a DIY PSU optimized for AT use, but with support for ATX soft power switching. It's a bit of an engineering task though. I can design a lot of it myself, but when it comes to magnetics (and, well, worldwide regulatory compliance), I have to throw in the towel. I don't feel too bad about it, though. Particularly with compliance, there's a reason most hardware vendors buy OEM PSUs from somebody else.
