I still bought my 795s7 (a cheap 16-core MoDT (mobile on desktop) zen4 box) anyways, but accepting that I would probably never get bios updates ever was a hard pill to swallow. I haven't had to deal with support for anything defective, but support as in available bios updates being so so so spotty is really unfortunate.
AMD is talking about replacing closed AGESA BIOS with open OpenSIL bios some day, and maybe perhaps possibly it means end users get some chance to maintain & upgrade bios themselves, eventually, possibly. Given how some vendors seem uninterested in doing the work themselves, this sliver of a hope would be nice to see happen.
I have the BD795M, the support is non existent and the BIOS updates are questionable. There exists a BIOS update but I've read it breaks more than it fixes. At current the temperature control of the fans is just abysmal. I can live with that for now.
