I think such contributions here on the WG are useful. As you probably
have noticed when we spent countless hours rotating bits in every
possible combinations, starting from a blank page is extremely difficult,
and most of the progress comes from contributors who are able to comment
on what they like or don't like in the design.

Whatever will be retained as a basis for HTTP/2.0, this exercise is
useful and may incite other users to provide very valuable feedback.

Best regards,
Willy
