This, so much. I maintain corporate, closed-source components which are central to my org’s mission and have to request radical changes on PRs submitted by other teams on a frequent basis. It’s really not “perfectionism” to avoid introducing serious maintenance issues and bugs long-term.

This is like jwz’s interaction with the emacs team decades ago — the story was that the emacs team was being unreasonable about merging some changes jwz/Lucid wanted. If you actually read the correspondence, turns out jwz wasn’t listening to review feedback. The feedback was completely technically reasonable from a maintainer’s perspective and jwz/Lucid just wanted the code merged without consideration for the emacs team’s future plans.

It is not specific to Rust of course, and it happens all time with open or closed source software, but it get interesting when people start to rant in public.

It is like marriage. Everything is fine in the honeymoon, even when it is not, but after that, things start to get a little messy.
