Martin,

well we could make it compulsory if that makes the proposal more likely to
be accepted :) We could mandate that all implementation MUST make random
fluctuations to the max frame size to hunt down and shame those
implementers who stupidly think that they need not implement a feature that
they do not need. [ Note that was sarcasm for those who don't get it ]

I think the WINDOW_UPDATE is well motivated to support the known use-cases
where multiplexing is not needed momentarily.     However the proposal
stands on without it and it could be removed if the WG explicitly
acknowledges that they will not support the issue that it is trying to
address (or comes up with an alternative).

But I'd ask the WG to mull on the proposal in total for at a little bit
before we abandon parts of it.

cheers
