Have the ability to remove phone numbers if other 2FA methods are present

Having both 2FA and a phone number connected defeats the whole purpose of 2FA, and it could cause the account owner to have their account stolen by extremely illegal yet commonly used ways such as "Sim Swapping". Having the ability to remove the phone number from an account if another 2FA method is present ensures the safety of people who don't want these attacks to cause them to lose their method of communication online.
