I was going to say “no”, but as I thought about it, I think maybe. My big concern was that Fedocal serves as a channel reservation system of sorts. But if we had a Calendar category with a topic for each meeting room (e.g #fedora-meeting), that solves that problem. The big missing feature then becomes sending reminders to the appropriate category or email address. So I could schedule the Council meeting by creating an event in the #fedora-meeting topic, but there would be no automated reminder like Fedocal sends. We could do without that, but it would be a pretty big usability regression, IMO.
