Let me be more specific. There were a lot of bugs specifically related to non-4k page size architectures. Arm doesn't dictate the page size so most of the Arm systems out there have defaulted to 4k pages. The Asahi wiki has a partial list of userspace programs that were (or still are) buggy and broken because they made simplifying assumptions about how different architectures work[0].
Maintainers of other non-x86 architecture have said that this is improving things for them[1].
