Of course, what could go wrong!!
Unbelievable, a chance to make a whole new standard, new system, new everything, but yet we still have the need to tie it to ancient protocols, only to find later it’s broken by design and we start adding all sort of duct tape solutions to make it “secure”..
This is either a completely and entirely stupid move by some boomers living in the 80s, or maybe, it’s intentional to enforce something insecure like a phone number/GSM as a “national ID” to easily track citizens and force them to have a phone number linked to their real life, and I think it’s the second one, the same reason why many “secure” chatting apps still require a phone number.
