While "RCS" is an obscure standard nobody cares about, "being able to send reactions, high-res photos, videos, and voice memos in text messages" is a pretty universal concern. iPhone support for RCS would let iPhone users have those features in conversations with the green-messages.

I never once wished I was able to do that, the only application for that would be to communicate with android users that for some reason refuse to use whatsapp, fb messages, telegram or any of the numerous cross platform that do that. Why would anyone want to do this specifically using the sms protocol?

Also, some of my friends and family aren't on those apps and exclusively use SMS/iMessage.

The point is that I don’t care about doing these things specifically over SMS. I send photos, voice memos etc over apps like whatsapp. It wouldn’t improve my life one iota to be able to do that with some legacy protocol.

What people care about is doing these things over something that is universal enough. In some places WhatsApp is so pervasive that it's that; in others, a mandated standard like SMS or RCS is the best you can hope for.

Whatsapp is universally available as far as I know. If people choose not to use a universally available, free and secure alternative, it would seem that universality is not the main driving factor.

Network effects are a thing. Mere availability of WhatsApp (or Signal, or whatever) doesn't do you any good if all the people you actually need to talk to don't have it installed.
