Is this a regional thing? I've multiple Twitter accounts, all of them with TOTP 2FA, and none of them has any information about my phone number.

You can effectively no longer sign up for a new account without a non-VOIP phone number

If you remove it after adding it to get through verification, your account is likely suspended a day or two later
