Well I don't know if it would be safer per se... I imagine you'd probably want some USPIS enforcement for that to happen, otherwise it might end up like phone calls (given it seems people understand caller IDs are spoofable and yet it's as big a problem now as it's ever been). But yes, it could've made it potentially easier to explain.
