> With the current text, if I receive something bogus on a push stream (after the preface) I'll have to keep the stream around (because the push stream may come out of order) waiting for a PUSH_PROMISE with that ID that may never come.

This sounds like the case @rmarx is looking at. I'd argue this is a good reason for the current design, frame processing should only take place once the PUSH_PROMISE is received. 

But I'd like to understand how framing could help avoid errors.
