This is a very US-centric (and maybe Canada) thing though? Most of the rest of the world doesn't really use or care about iMessage, even on iPhones. So, I think it's rather
-US- iPhone users very often don't want to have SMS/MMS users in their group chats.
The rest of the world is using WhatsApp, WeChat, Telegram, Snapchat, LINE, etc. for group chats (for better or worse), even on iPhone.

If what you say about “the rest of the world” using other messaging apps is true, then yeah, it probably is North America–centric. So what? Are you agreeing with the OP who didn’t see any point and advocated that GrapheneOS “totally ignore RCS”?
GrapheneOS already supports WhatsApp, WeChat, Telegram, Snapchat, and LINE. What’s wrong with improving OS support for another widely used alternative, that for all its faults is mostly better than still another widely used alternative (SMS/MMS)?
There’s a thread on the GrapheneOS forum titled “Using RCS with Google Messages on GrapheneOS” with 2,192 posts in it. Clearly there’s a lot of interest in using RCS on GrapheneOS!
