I just announced my intention to introduce hard Rust requirements into APT, no earlier than May 2026.
I believe it's important for Debian to be able to move forward and not b-e blocked by the concerns of unofficial retro computing ports.
By introducing Rust into APT, we will be able to convert security relevant parts like .ar, .tar, .deb file parsing and HTTP interactions to a memory safe language; all things that had seen a bunch of memory safety issues in the past.
