It might be that you looked in the wrong place. I didn't check the RCS-situation in a while, but last time I checked (~1.5y ago) the Europe operators who haven't deployed RCS already (3-4 operators) dropped investment plans and decided to support RCS via Google's RCS cloud-service instead, mandating the use of Google Messaging as device-client.

(Google acquired jibe, a major company developing RCS clients/servers, and started rolling their own RCS-server and moving almost all vendors to the same client)

My expectation would be that by 2022 the majority of Europe carriers support RCS, not as an in-house service but by using either Google's cloud-based RCS or Samsung's RCS and their respective device-clients (with Samsung on steady decline).

The situation is a bit opaque, but if you look deeper on the device-side, RCS is no longer a carrier-controlled service. Google and Samsung combined control >90% of the client/server development and operations. They surely both align via the GSMA, but I doubt that the GSMA has actual control over the roadmap of RCS any more today than it had control over it ~2 years ago (which was close to zero)
