None of these are a reason to not to also have a different number that you can publish publicly without giving someone your phone number. You can have your phone number for everyone in your phone book and a one way derived or random number for everyone else.
> When I first reach out to someone on Signal I know the person I'm reaching out to is the owner of the identifier I used unless their phone carrier is actively compromised when I exchange the first message.
Compromising is in this case rather common in sim swapping and spoofing (you can barely even call it spoofing). Phone numbers are not useful as some sort of continued point of trust. And I doubt Signal uses it like that under the hood.
> What more do people want?
Before you complain about other people maybe you should give other people the courtesy of reading what they wrote first. I have already said what I want, a public id I can publish on for example GitHub without the implications of publishing a phone number. Implications which anyone with a relevant opinion should already understand.
