Allowing developers to merge directly into any mainline is a bad idea. Everyone makes mistakes here and there. I have senior developers STILL committing things they didn't intend to (that have been using git for years), and so a chance for someone to review it helps. But maybe they still make mistakes because they know someone else is going to look at it, I don't know.
