And, if it's something that's worked around in software (meaning, it was a hardware issue), that might have issues for things like Asahi Linux, which probably won't have that workaround in place.
Arguably it would impact the support for other OSes, especially alternative ones who'd need to reverse engineer the workaround and/or write their own to get the network stack working.
It could also fall apart the day Apple decides this machine is not supported anymore, and their next OS won't have the correct drivers anymore. It's their prerogative, but will sure suck for the machine owners.
