Yeah, I'd love that too! I know there have been people pushing on this, but AFAIK, it's stalled on "how do we package Rust applications in Debian."
(I don't use Debian and I'm not terribly familiar with their policies, so I'm not really familiar with the details.)
https://crates.io/crates/debcargo is also a big help.
