Yes, you right. I don’t talking about hiding revisions, I want to remove them. Who actually need a dozen of revision all the time? Don’t you think this is waste of resources @codinghorror ?
Anyway, as I said before take it waste or not, we should be able to remove these revisions… If there is no feature request like this, let me make one here 
(Forgive me if I say something rude, I’m not native speaker)
