I'll have to say that I can understand the desire for the former.
Oddball or too old hardware that the vendor isn't willing to do tech support for is definitely not going to get developer attention; you're definitely on your own if you run unsupportable hardware (unsupportable = hardware the vendor is either unwilling or unable (through lack of having any of that hardware for testing) to support).
But there are those who will ignore the 'supportable' list, install it anyway, then publicly gripe and complain about how terrible the product is. Easier for the vendor to reduce their supportable footprint. Thus Apple's move to their own silicon for Macs; believe it or not there are people who will do a hackintosh and then gripe that Apple won't support their macOS install..... If you can't install it you can't gripe about how badly it runs on unsupportable hardware......
