Hi Alexy,

All your DISCUSS comments are valid and easy to fix. Unfortunately I'm
on personal travel this week so can't update until next week.

Assuming we need a new version, we will of course also review your and
other's COMMENT comments.

Specifically,

I have no objection to that but since it's a (minor) protocol change we
would definitely need to run it by the WG.

Thanks
