> If you intend to know who’s texting you, then you need to provide permission to contacts as well. It would be pretty ridiculous declare contact scopes for each person that you message. I’d have to declare hundreds just to read old Messages.
This might be a usage difference, but instead of handing over the entire contact permission I’ve generally found it suitable to instead use the contact scopes feature to limit my exposed contacts in Google Messages/other SMS or instant/internet messengers.
This way I know if one of my “trusted contacts” is trying to text me, but I don’t have to hand over my entire phone book.

> To get RCS to work, you need Play Services and Google Messages both installed on your Owner profile. You need to also hand over network, phone, and, SMS permissions, and likely device identifiers to Google (depending on carrier).
Of these issues I think having to expose your persistent device identifiers to Google is possible the worst issue.
