as a co-author, I understand the concerns raised by Brian and I agree
with Peter's proposals to address them
We can clarify that the goal of this draft is not to endorse the
long-polling techniques (but rather to present the known issues and the
counter-measures that try to mitigate these issues)
I do think we should not go further and add a judgemental statement
along the line of Brian's comment ("This is real example of protocol
abuse. HTTP wasn't designed for this and doesn't do this properly")
but I think that we can more neutrally add a sentence stating that the
proposed techniques stretch the original semantic of HTTP and that the
HTTP protocol was not designed for this use... which is a fact rather
than a judgement.

Which is why folks who are currently using long-polling techniques are
actively contributing to the HYBI WG.
The draft is non-judgmental,
and that might be a mistake.
The draft is Informational and therefore isn't really in a position to pass
judgments. All it is trying to say is: we know that long-polling techniques
have many issues, but if you're going to use these techniques then at least
try to do so with some modicum of intelligence. We're making the best of a
bad situation, and if the HYBI WG is successful then hopefully people won't
feel the need for long-polling techniques in the future.
Personally, if I was in the IESG,
I'd be considering a "holding my nose" ABSTAIN ballot
I'll be balloting RECUSE.
unless some
text stating that the methods described are really bad ideas
was added.
I'd have no problem with adding a sentence or two to the effect that
long-polling is a temporary hack that emerged from the applications
community and will hopefully be superseded by technologies that aren't so
abusive of HTTP. I'll confer with my co-authors about wordsmithing, if they
agree that it's a good idea to add such text.
