There's a difference between "must give >= 3 initial uni credits" and "must always have enough credit to open the control+qpack streams".  Do we have consensus on what the requirement should be?  I'm inclined to say it's the former.  Don't burn your credits on grease/push/extensions if you're going to need the other streams.
