Exactly as I predicted there is already an SE API in the workings from Google.
It is simply about connecting the dots :-)

I'm aware that hardware-backed keys are out of scope for the current round of WebCrypto work, so I don't expect this to be ready for standardization for some time. Nevertheless, I've got a proposed extension to WebCrypto to support Fido Alliance (fidoalliance.org) universal second factor (U2F) devices:
https://docs.google.com/a/chromium.org/document/d/1EEFAMIYNqZ7XHCntghD9meJwKgNOX7ZN-jl5LJQxOVQ/edit# I apologize that the proposal may lack some context, like, just what is a U2F device, and what language does it speak? I promise update it with pointers to public docs once they are made public. In the meantime, I'll act as a poor substitute by answering questions myself, either in the doc or in email.
I'd appreciate any feedback you might have. Thanks very much,
