I don’t understand why PRs are being discussed here at all – doesn’t anyone serious use trunk based development with code reviews? How is that different from a PR? Seems like we need to disentangle the discussion of whether code review is good from whether feature branches vs trunk based dev are good. Those are completely unrelated questions to me.

I think there are a lot of interesting questions about using feature flags (a baby branch) vs actual branches. Personally I’m pro flags and anti branches, after a lot of experience in developer tools and CI.
