From the last link: > a low-friction means to strongly re-authenticate on client devices having platform authenticators. IE: People in big tech think everyone on the planet should have at least 2 modern devices and sign in to their big tech cloud accounts on all of their devices. I'd also be willing to bet there's no thought given to de-authorizing a key, so when my parents/siblings/niblings recycle their 5+ year old devices without wiping them first they better hope there aren't any known security flaws for those devices.
