Hi Cary,

thanks for reaching out.

The obvious blocker is availability of hardware. We don't have build
hosts. The other question would be if those build hosts could keep up
with the speed of the other architectures. Currently all supported
architectures are about the same speed, so we can build all packages
synchronously, which has helped a lot with keeping repository quality
up. Looking at Debian's riscv64 build hosts, they are often much
slower than the others.
