I didn't say it wasn't a pain point or that there weren't challenges. I said I don't hear about people complain about how Rust programs are packaged. Not that the packaging of Rust programs (among others) itself doesn't present interesting challenges depending on the policies of a particular distro. Archlinux, for example, has far fewer problems than Debian because of differences in policy.
The poster I was responding to was literally posting false information. I'm correcting it. This doesn't need to turn into a huge long sprawling discussion about packaging Rust programs. The main point that I was making is that lock files do not prevent Rust programs from being packaged. bombolo then went off on their own little tangents spouting nonsense without bothering to acknowledge their mistake.
