it is definitely not difficult, but it is a special case and as any special case forces an increased complexity in the possible codepaths, even if not that big in this case. 
I am making my argument for the sake of consistency mostly, and for the fact that I believe it would also help to better define error handling.  
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. 
So I believe that framing could help error handling as well. 

I do not have super strong feelings about this proposal but at the same time I'd like us to try and recall what the motivations are for the current text and for making this special since it was a while back and personally I can't recall what they were.
