Not being able to backed up, to storage of the user's control, is the issue. I don't want a Google or Apple backed phone to be the only hardware token secure enough to protect my key. I want these devices to, RIGHT NOW support copying their keys to another device that neither party can control. I want an open standard that people can implement in a less-than $50 secure hardware device that I can duplicate these keys into. I think the UX of a "Key Safe" that is offline, physically securely stored, and can manually + securely have keys copied into, or copied off without Apple or Google's intervention would solve a lot of concern about the very real lock-in that's in play right now.
