Google Messages app sends a lot of spam here in India if RCS is enabled. I confirmed this with some of friends who experienced the same thing.
Telecom Regulatory Authority of India has an app called DND which lets you register your phone number to opt out of marketing and promotional SMSes. It works really well and in case someone sends you a promotional SMS despite opting out, you can report them to your SIM provider (or carrier) and they are legally required to take an action.
But as soon as RCS is enabled, you will magically start receiving a lot of spam messages with rich text and link previews. Unfortunately, the DND app cannot see or detect those messages which means you cannot report them.
