Thanks for looking into this, it's very much appreciated.

My main worry is that "acknowledgement" seems to imply "merge as is
(plus or minus quality standards)", but no mention is made about
feedback on design.

I fear that cross-posting to a dozen mailing lists is going to make
discussion and feedback problematic from the perspective of the people
proposing a new protocol, as well as people commenting on it. Having a
single place for discussions would be a good thing; that's typically
what the wm-spec list was meant to be used for, back in the EWMH days.

Maybe we should resurrect the wm-spec list for Wayland protocol
discussions, now that EWMH discussions are not "hot" any more, and use
the list of addresses below as a mechanism to contact interested
parties and direct them to wm-spec — if we want to avoid every person
involved even tangentially to toolkits and Wayland compositors to
subscribe. Unless, of course, you want all discussions about Wayland
protocols to happen on wayland-devel, which would be equally good to
me, but may escalate the traffic on the list.

Before you answer my questions: I'm fully aware that you have kind of
outlined a process in the commit message, but it's probably worth it
to have the same process outlined in the document that people are
going to read. :-)
