Well I'm sure the EU will be delighted to hear this.

As explained here [0], it will soon be mandatory for all large messaging apps to interoperable - as part of the DMA (Digital Market Act). As to how that will be done technically, nobody knows, but RCS is definitely a standard that could be used.

I bet a different standard will be created instead. RCS puts carriers back into the equation, while major services (or as the EU calls them “gatekeepers”) just want to have as much control as possible.

The EU requirement is for platform interoperability—e.g. sending a message from WhatsApp directly into iMessage, and vice versa. How would the RCS implementation that Google is asking for, which is carrier-based like SMS, satisfy that?

Even if Apple and Facebook implemented a private message peering service and chose RCS as the protocol, I don’t see how that helps Google.
