I can sort of see the rationale for this, but it's been a long time since I've worked anywhere where this was feasible even 50% of the time; nobody wants fragments of a feature in trunk, and the codebases tend to be inflexible. "Commit to branch", sure; branches are cheap.

This is more reasonable. Working without review leads to worse fiascoes the longer it goes.
