I've thought about these type of malevolent actors also.   I think that
there is nothing in the current draft that prevents them from acting in
this way in any case.   If they want to write custom clients to write
IPoverHTTPv2Headers, they can and probably will.

But my thought bubble is aimed more at naive actors, who are using normal
clients, but who's cookies are getting large or are including big kerberos
keys etc. etc.      Just because their headers creep up to 32KB say, should
not mean that they get 50% more fair share than a stream that has no
