Beware that some HTTP/2 clients vomit (IIRC with fatal TLS alert 10
after sending client Finished) if the server sends 0.5-RTT data (no
client certificate request). I do not know more specifics, but I
suspect that at least in some cases, there is some "anti-virus" or
"security" product involved on the client side.
