Description
Which is basically any endpoint under https://matrix.org/docs/spec/client_server/r0.6.0#getting-events-for-a-room.
Synapse does this in places for things like /joined_members, but typically it would be useful to not have to masquerade as a user to get information about a room.
Doing so would be a backwards incompatible change as any bridges relying on failures to fetch events for permission reasons may break.

Research direction
Review the Client-Server API section on getting events for a room, including the listed endpoints and Synapse's existing /joined_members behavior. Define the permission rules for appservice users when another appservice user is joined, and assess the stated backward-compatibility impact before updating the specification.
