Having a per-meeting special list has an obvious and reasonable basis.
However it makes each meeting's list a special case for IETF
administration and for attendees.
Possible variations to consider:
I think the best variation is automatic resgistration to meeting list,
but to use this list only for urgent messages (either from secretariat,
or allow from others bu moderated to allow only urgent messages
All messages about download speed of cookies and healthfullness of WiFi
should be directed to discussion list. This way everyone's existing
function as desired, and the emails are archived so that we can later
meetings from the point of view of cookie speed, WiFi health, etc.
