I’m not convinced about the reasonability of this threat model where leaking messages is fine but leaking the telephone number means game over.

However, I do understand that sharing one’s phone number is problematic for some users.

With that said: Until Signal implements user names in their system, please note that the user is not required to sign up for Signal with their primary telephone number. One could use Google Voice or a prepaid SIM card for example.
