#1425 Allow restricting MAM access in MUC depending on affiliations
Description of feature:
Allow MUC owners to configure the affiliation needed to query MAM at all in (or outside) a room.
Prosody (and possibly other implementations) currently allow fetching MAM before joining a room. Prosody specifically rejects outcast users if they appear in affiliations.
I am personally interested, as an admin and user of the room, in preventing anybody allowed to join to query MAM without me having a clue.
I first suggested forbidding anybody not joined to query, but this also worksforme (until we add everybody in affiliations automatically).
