Yeah, I can definitely see this being an issue going forward for quite some time. The existence of non-Apple ARM devices should hopefully lead to general interest in addressing these issues, but there's so much hardware and software out there, and only so many devs with the time, interest and access to fix them.

On the other hand, I suspect people will start making choices for their hardware/software that maximise compatibility, as they already do for Linux x86. ("Don't buy NVIDIA if you want functioning Wayland", etc.) It'll be tough, but things will hopefully get better over time.
