You sound like people defending PGP when everyone knew there were major downsides and usability issues. How can keeping phone numbers as the only option be more important than everyone being able to publish "Signal:39475638" on someplace like GitHub? Is the phone numbers part of the encryption somehow and you absolutely can't use some other number even in addition to it? Because I refuse to believe you don't understand the downsides of phone numbers and I know you understand the protocol is good enough were it is relevant. So surely then there has to be some technical limitation because what other legitimate reason is there?
