Been waiting for this for a long time! Another thing that’s been on the horizon I’m eagerly waiting for is p2p. They’ve been working on Dendrite, which is a much more efficient Synapse, and the goal is to be efficiently running it to effectively running it on your own device as like an invisible self-host. They’re working on MXIDs as well so @hostname.com wouldn’t be a thing anymore. P2p with all this other tech would make Matrix really the privacy holy grail imo.
