Scarletphones should have the concept of purgatory/archived contacts. never suggest them, never tell me when it's their birthday, never expose them to 3rd party apps, but ultimately keep them on file and match their number to their name if they do ever call or text again
Ayush Agarwal@scarlet #GrapheneOS offers Contact Scopes which kinda does the inverse — you can choose the contacts which should be viewable by individual apps.
