do we want new users to follow pubs?

Technically it is possible to onboard people without pub invites. It’s just not simple of you are not in the same room/doing it async. If i and the new uxer both Post contact: Messages to follow each other she can connect to pubs and other peers without ever using an invite. Our friendship will be enough for pubs (granted, with hop > 0) to accept her connection and sync.

I think the iffy part her is the async setting since you can’t follow them until they made a key.
