wow the signal usernames design is good actually:

• username is exclusively an "adding you" thing
• this is because they are one way of getting an invitation to chat with you
• there's also randomized and resettable links that can be shared for this
• usernames must always have discriminator numbers, which can be freely selected
• usernames aren't shown to anyone you are in chats with
• by default phone numbers are no longer shared with chats

this seems to have basically Fixed it
