RCS E2EE and Group E2EE are live which makes this a less dangerous attack surface / a less useful ad data reservoir. Google Voice users like myself are SOL but I've never had pretenses that my messages there are private. They're probably stored in plaintext even, there's a lot of 15+ year old GrandCentral cruft underpinning Voice even to this day (speaking only as a user).
