Just to expand why I cannot live with 16 bit lengths.

I can already see valid use-cases today that exceed 16 bit lengths.   We
have decided that 64KB kerberos tickets are acceptable and necessary to
support, so a kerberos authenticated proxy talking to a kerberos
authenticated server will need two such tickets and that will not fit into
a 16bit header block.

So that use-case will just drive fragmentation of headers (continuations by
another name), which breaks the entire purpose of this proposal.

Either we have frames large enough to carry all acceptable headers - or we
need to go back to basics and come up with a framing layer that does not
treat headers specially.
