If you want to propose a session for the main room of the MediaWiki Developer Summit, then make sure it is fit to compete for a slot at https://phabricator.wikimedia.org/T85632

RobLa and I are coordinating this exercise and we want to have the main room fully pre-scheduled by the end of next Monday, Jan 12.

The rest of the schedule is open, meaning that anybody can book a slot as long as it is available.
