* Setting video owner as room owner as side effects. Like leaking the instance moderator/admin list. And maybe others.
* So we rollback this feature, waiting for a better way to allow room admins/moderators to change room settings.
* As a consequence, users that are not Peertube moderator/administrator can't change the slow mode configuration without deleting/recreating the room. This will be fixed in a later plugin version.
