- Lots of 3rd party apps are "noarch" anyway (QML + Javascript, mostly - same package regardless of the CPU arch). - Supporting Aarch64 is basically just adding 1 more available target on their OpenBuildSystem compile farm. - We need multiple archs due to Atom's 486/IA32 anyway - There aren't that many 3rd party apps with binary code anyway, compared to Android or iOS. Lots of them are opensource and even if the original author is unavailable, someone else could easily fork the repo and recompile. Only the few closed-source apps, with a binary component, whose dev is unavailable, and that will need a Aarch64 recompile would be affacted by the switch.
