>I typically ask for the devs to push their code into the repo incrementally That's fine provided each of those PRs gets reviewed and merged almost immediately but if you don't do that then either the developer has to create a separate branch for each incremental improvement (horrible) or let them mount up into a monster pull request (also horrible). Some changes also kind of need to be large in order to not break anything (deep architectural changes).
