I might be misunderstanding here but... what you're saying is that Rust programs can still have bugs? Isn't that the same as other programs except Rust prevents the most disastrous and common bugs that lead to most CVEs?
If I got that right, how is "it's still not perfect" an argument?
Agree with the Cargo objection.
If perfect isn't needed, we might as well stick with the 20+ years old mature codebase, there's no need to move to another language. I mean the "code to parse .deb, .ar, .tar," is done and whatever memory bugs should've been already fixed .
Use Rust for evergreen projects by all means, just leave mature tested systems alone, please.
I don't follow how from "better but not perfect is better than worse" you conclude that.
OK? So, is your position that Debian is only for software that's old enough to vote?
Or maybe Debian should never rely on any software written after 2015?
