Re: New Version Notification for draft-mcmanus-httpbis-h2-websockets-02.txt

"due to its multiplexing nature" in the introduction section looks
redundant.

Given that we drop the Sec-WebSocket-Key/Sec-WebSocket-Accept header
considering that SETTINGS+:protocol is sufficient to ensure everyone on the
path understands WebSockets (tunneling), I suggest that we also drop the
client-server frame masking while also allowing masking as optional for LBs
that don't want to parse/rebuild frames but forward everything after
upgrading.
