// it's still just (Alice,Bob) but then we won't be tracking Charlie -- is this okay though? It's device keys
// which are only relevant when actively sending events I think? And if Alice does need the keys she knows
// charlie's (user_id, device_id) so can just hit /keys/query - no need to keep updated about it because she
// doesn't share any rooms with him.
// Ergo, we put them in `left` as it is simpler.
