Re: Working Group Last Call: Incremental HTTP Messages

I've raised a minor issue on GitHub (
https://github.com/httpwg/http-extensions/issues/3302). It's a question
whether intermediaries, that recognize but don't support the header field,
should remove `Incremental: ?1` when forwarding the message.

Except for this small clarification, I think the draft is ready to go ahead.

Best regards,
Marius Kleidl
