Apple made a partial implementation without the full feature set and no support for the current Signal-based end-to-end encryption used between Google Messages clients.

GrapheneOS has working OS level RCS support from AOSP and Pixels. It's possible to use Google Messages on it. However, it partially depends on having privileged OS integration and doesn't always work well for people.
