Why do we need to check if the user has forgotten the room? I guess it's because the user might have left the room and forgotten it but we are still getting new messages with them joined to the room over federation?
Should we be checking whether the user is currently in the room instead?
I'd really like to have some comments here to explain what we are doing and why.

To be honest I just copied from the filtering code. I'm happy to drop it if we think we can?

I think you are safe to ignore the forgotten stuff if we are only looking for rooms that the user is joined/invited to. I think you can only forget a room that you have left?

The filtering we do with events we're calculating the push rules for is much simpler than the general case as we know the users are currently joined in the room. This changes the
filter_events_for_clients_contextto take advantage of that fact (which was only used from push)
