It's really awesome how far it has come; stellar work.
It's weird though, every chat app I look at has this unfortunate structure with "some server" component hosting all the data (or at least facilitating delivery of it), which necessitates the additional layer of e2ee like MLS or Signal Protocol.
I really want to get rid of that layer and go direct; device to device. No need for those protocols and the complexity they add if there's no middle man touching your sh!t.
