Suppose GrapheneOS becomes highly popular. Then I have to fight the average Joe who insists RCS is fine enough.

I understood from other comments that RCS is the default communication channel in N.America an I can sort of see why you want to give people a somewhat less worse option here than Google's Messenger. But RCS should not be the default imho, because lazy people gonna be lazy. So I hereby endorse you to gently push newcomers towards a safe and privacy friendly default by pre-installing Signal or whatever meets the bar and give it a prominent place.
