Yep, your patch makes perfect sense considering the tree as it is today. But if you agree with my sense of what it *should* be, I think we should leave things as they are, or work on moving everything towards __devinit (I'd be thrilled if you wanted to work on that :)). Otherwise we'd just be changing things to __init that we'd have to change back later.
