I agree that unbounded headers are a compat issue - 16 bits is going to
break some tail somewhere. So we need a continuation like mechanism.

My first choice is to continue with h2-13 as is.

My second choice would keep continuations but address some of the other
 1] make frame sizes other than 14 bits configurable by an extension
 2] get rid of the reference set based on the data, and require colon
headers to be sent first and not in continuation
 3] make hpack inside continuations stateless and allow them to multiplexed
with other frames

That does address the header hol blocker issues that current exist (though
I don't think it is much of a practical problem which is why I am fine with
proceeding without a change).
