Thanks all for your comments.

First, please note that I wanted to discuss the question in the context of
WS/HTTP/2.0 layering. Not about redesign of RFC 6455 itself.

I asked this question since the length header is the biggest field when
encoded into HTTP/2.0 HEADERS format. Whether we can eliminate it or not in
WS/HTTP/2.0 is one of the most important points to evaluate the plans
employing HTTP/2.0 HEADERS.

Though the ranges the length headers represent differ (HTTP/2.0: 14 bit, WS
length format: 63 bit), it seems everyone can live without a header of
"original WebSocket frame size".

Please reply to this post if you have any objection, but please don't write
objection to use of HTTP/2.0 HEADERS itself in this thread.

Thanks
