well, I think if you start with this kind of bureaucracy, you're doing it wrong. It's not funny. Also, if your app is down, clients calling and you need to fix it fast. If I need to remember this rules to fix this, people will kill me, or I will kill myself :p
After a few days practicing this, it becomes second nature, and doesn't hold you up at all. Commit histories also become much quicker to parse through, especially with "log --oneline".
I notice no hindrance on my speed because I write good commit messages, and always value them when I one back to them.
