My initial idea is to kick off discussions in the sessions, then
continue at BoF or whatever if not finished in time.  This is often
more fruitful than too lengthy discussions.  You can cool down and
reconsider the idea.

Yeah, but we should apply a strict rule in such a case.
The preparation must be done before the session.  If not, the topic
should be started without the video.  Also, the topic is cut strictly
in time.

As mentioned, we have already one additional slot, currently planned
for my channel-mapping API topic.  I can shorten the topic and the
almost whole slot can be used for other discussions.

And, if needed, we can ask for a slot/room for BoF beforehand in
