Is not very compatible with printlog-debugging. I'd rather encourage devs to prod around as they go if it benefits them, which causes grief for either them or reviewers in the end if they've internalized what you just said.

Explicitly adding internalizes a personal review process as inherent part of the push process, instead of something you attempt to force on top later.

It's better with a collaboration workflow that limits the span of time with expected discipline, imo.
