The more fragmented your community, the harder it is for software to work consistently across all of them. Intel vs AMD has plenty of obscure issues (see "rr" project, and all the issues getting that debugging tool to work on AMD even though it has the same instruction set).
Sound, WiFi, Ethernet, southbridges, northbridges, PCIe roots. You know, standard compatibility issues that having a ton of SKUs just naturally makes more difficult. Having a "line" of southbridges / consistent motherboards does wonders for compatibility (fix the BIOS/UEFI bug in one motherboard, fix it for all) in Intel/AMD world.
But just as AMD has AMD-specific motherboard bugs, and Intel has Intel-specific motherboard bugs... I'd expect Graviton to have its share of bugs that are inconsistent with Apple M1 or Ampere Altra.
