A deployed Python distribution generally has .pyc files for all of the standard library. I don't think people want to lose the ability to call help(), and unless I'm misunderstanding, that requires docstrings. So this will mean twice as many files and twice as many file-open calls to import from the standard library. What will be the impact on startup time?
