Raphael: Do you have implementation to share?
Rohan: Travis, ok with closing ticket on Matrix extensible events?
Rohan: Thoughts on leaving implicit id, given potential value for
sharing message history?
Konrad: #3 is still the pseudonym approach, but with handshake

Brendan: What is the value of having pseudonyms, if they can't be

Konrad: I think we agree we want a non-protected mode, and a
metadata protected mode. Question is just which mode for protection.
Proposal to wait for Brendan's I-D then decide.
