Arch is working to officially support ARM and non x86_64 archs.

https://rfc.archlinux.page/0032-arch-linux-ports/

That RFC says "New ports are added by proposing them in an RFC. At least two package maintainers have to lead a port to ensure it will be developed longer term." but I'm not finding any RFC for ARM support, so can one say work is really officially happening on ARM?
