I really, really hope this leads to development of data portability/server migration options. When I set my homeserver up, I chose Synapse as I didn’t know about the other servers. Now that I do, and would like to switch away because of Synapse’s performance problems and the new CLA stuff, I realize I and all my users are fully locked in, and would have to start from scratch (lose all chats, profiles, etc) to migrate.
