RCS is basically spam-only messaging at this point. You can enhance your messaging experience by just turning it off.
Google is doing a really good job catching and blocking spam as far as I'm concerned. Even scammers aren't trying their luck over RCS in any way significant compared to Telegram, WhatsApp, or even iMessage.
The main thing Apple/Google needs to fix is RCS group messaging where spammers change the name of the group message to "Apple" or the business they're trying to impersonate.
