Absolutely! One of the key goals I had in the RFC proposal was to effectively pipeclean the path for other non-x86_64 archs, not just AArch64.

For AArch64, you are absolutely right, there's a lot of useful targets already ascending the Tiers, aiming to get to Tier-1.

All this will help AArch64 in particular to ge the top-class CI focus that the Rust community has built. Bodes very well for safety and security sensitive ecosystems, IMO.
