Sorry but I find the prospect of "unwanted" server pushes quite 
alarming.  This phrase and a previous mail today which indicated that 
server push would be unilateral made me write this.

Surely all server pushes should be solicited by the client first?  E.g. 
the client indicates it wants pushes.  Until it does that, it doesn't 
receive any.

Having to choke them off seems like a bad choice.

My gut tells me strongly the protocol should be "polite".  Neither end 
should ram anything significant (IOW "large") down the other end's 
throat without prior consent of the receiver (so this goes for large 
bodies on requests too).  Requests are deemed consent, so a server is 
entitled to respond.  Large request bodies are currently rude 
(unconsented) and it actually creates a lot of problems with auth.
