MUC: Don't default component admins to being room owners This change has various technical and social benefits. If ownership of a MUC is really needed, it can be gained using the 'Set affiliation' ad-hoc command or prosodyctl shell. Example client incompatibility with the old behaviour: - https://github.com/monal-im/Monal/issues/1085

 ### MUC
 
+- Component admins are no longer room owners by default. This can be reverted
+  to the old behaviour with `component_admins_as_room_owners = true`, but this
+  has known incompatibilities with some clients. Instead, use the shell or
+  ad-hoc commands to gain ownership of rooms when necessary.
 - Permissions updates:
   - Room creation restricted to local users (of the parent host) by default
     - restrict_room_creation = true restricts to admins, false disables all restrictions
