At least in the past anyone with SS7 access could already do that based on either of those identifiers.

Phones, especially smartphones, are pocket spies. If you need privacy, don't take them with you!*

There is no such thing as a privacy smartphone.

* Honestly if you want a private conversation don't have any kind of phone or laptop in the same room.

I get that, and carriers are definitely stupid. But preventing people from gaining SS7 access is much easier than fixing a broken protocol in use by many devices. Blocking SS7 access is something carriers can do. Fixing 2G is just not possible, and anyone can break it, right at this very moment, with a tiny bit of hardware.
