How so?

As another person pointed out, this is quite literally what krypt.co's Krypton app does and it integrates with existing U2F/FIDO standards so either a hard or soft device can be used.
I don't want Bluetooth, NFC or software u2f devices for security reasons, but I also think they could each have additional support problems if given to family members.
The ideal option for me would be an applet on a smartcard in my phone's 2nd sim bay and a hard power toggle for the 2nd bay. Then I suppose my phone could also provide proxying of u2f as a USB device.
But last I looked Android was blocking access to simcard slots for general purpose..
it's awkward enough for desktop use that push to mobile is a superior UX
To use my own insight: regular joe does not want to buy an expensive product and install some hardware. (the "cheap" $20 ones are literally worse than useless. but even $20 is too much.) 2FA's future is in touchID (integrated into touch bar on mac) and push to a phone app. The latency of push to a phone app is more acceptable than the confusion and vagary around adding an expensive usb key that you don't understand and then doesn't work on your mobile anyway.
