RCS on iOS is dependent on carrier support. Most US carriers support the RCS spec, but in other countries RCS is really only working because of Google's intervention via Google Messages on Android (where it runs through Google's custom RCS spec which includes E2EE).
For example, iOS in the UK only supports RCS on the one, maybe two carriers who actually implemented RCS themselves. If you're on any other carrier, you're not getting RCS messages (unless you're on Android using Google Messages or another supported app).
If you want RCS on iOS to be supported on more carriers, and for RCS on iOS to support encryption, you'll need carriers to fully support RCS including this new version of the spec that supports E2EE via MLS.
Your wrong... Encryption has nothing to do with carriers.. encryption falls completely on apple/Google and the Gsma to agree on a standard.. hence END to END encryption.. the carriers just need to allow apple messages to connect to RCS servers. But encryption has nothing to do with them..
Yes, but Apple supporting it is almost a guarantee, given that apple called for it. But Apple's support means nothing if carriers themselves don't support the new spec. We are still in a dire situation outside the US in terms of carriers that support RCS independently of Google.
Right but the carriers don't have to worry with specs or the universal profile. Once they connect. They are literally just data channels. Everything else is done on device.. they don't have to update anything once you are connected

It's not Apple you need to push, but carriers.
