Arch package manager here, there is ongoing work behind the scenes to support multiple architectures (aarch64, riscv, etc), but as our volunteers (myself included) are doing this in our free time, progress is up in the air.

That's great to hear:) Given the long-term existence of eg. https://archlinux32.org/ and https://archlinuxarm.org/ I had always assumed that this was purely a question of policy and that Arch had no interest in supporting anything else. I found https://rfc.archlinux.page/0032-arch-linux-ports/ ; is there anything else I could read to catch up on the state of things?
