You'd share a username, which is way different if you ask me. I don't mind sharing my username, Kusimulkku, here but I wouldn't want to share my phone number and real name.
If you use the username to get into contact then your phone number isn't visible to them iirc. Same other way around, your username isn't visible to people you've got into contact with a phone number. So no need to worry about your phone number leaking or your friends and family seeing that you also go by "MonsterCock2000" or something.
What I mean is that the username only serves to connect two users. But the profile they then see of each other is their standard Signal profile, with whatever name and other info it contains.
At least that's how I understood their blog post
I think that might be true, but you could just have your first name as your name or something less private than full name + phone number etc.
