I think of the term "state of the practice"

Same thing happens with renting apartments. Slowly but surely, conveniences like apartment-phone-app (to open doors, to access mailboxes) get accepted by people and then they "throw the switch" and make the remaining 3% do it. Or maybe new renters must accept it to move in. And then they can deny access to apartments imeediately, track their residents, match with online activity and more...
