| In order to not break old clients | ||

This doesn't seem to add up - if there's a new event type then the redacting client won't even send an m.room.redaction event. Unless the homeserver is to synthesise an m.room.redaction event, there's nowhere to add the redacts string; and if it's to synthesise the event, it should be spelled out here.
