x86_64 is the only official Arch Linux. All other ports are unofficial. They are community projects where many of the members are the same as the main Arch Linux.
I think it's basically for the same reason as why they dropped 32-bit x86 support about 8 years ago. Not enough users. (That resulted in the unofficial Arch Linux 32 to maintain support.)
I think the reason is they don't want to become debian where deciding anything takes foverever. Another architecture is a liability, so it lives in another "project" that official arch is not committed to.
I write this from arch on arm (orange pi) thingy, btw
