I noticed that clients that want to retain per-request control of
authority (anything that might want to use multiple authorities
without opeing multiple connections) has to eat 1-RTT penalty per
request due to not being allowed to send USE_CERTIFICATE frame
(one can speculate on proper value very well) immediately after
HEADERS (and AUTOMATIC_USE destroys per-request authority control).
