Profiles may be designated by a UUID.

Is that a good idea? Can someone intentionally create a UUID that collides with another to break things?

If they do, what are the consequences?

Should UUIDs be something that ever leaves a user'd device? Should the user's chat app assign uuids?

Should we distinguish between "foreign" UUIDs and "own" ones?

Should there ever be UUIDs going over a network connection, or should we prefer incremental counters or something?

Actually, if we follow SimpleX's ideas, isn't kinda the point of it all to not have global IDs for profiles?

Honestly, should we even use UUIDs? They give a false sense of security, perhaps.

Local identifiers might make more sense... in that case even incremental ones would - albeit that that might interfere with import/export of profiles
