Is there a WebAuth polyfill with a U2F fallback please?

Hi !

I follow your work on Mozilla about WebAuthN RUST development, and I would like to ask you if there is somewhere a Web Authentication polyfill cross-browser, with ideally a fallback to the U2F API (I've read on a BugZilla ticket there will be a compatibility to move registered U2F devices to WebAuth).

Thanks for your help and your work ! :)

We definitely need one. The only one I know of -- but it's still mostly a stub -- is https://github.com/apowers313/webauthn-polyfill.

Thank you @jcjones for your reply. I've already posted the same question 2 months ago on this polyfill because it wasn't updated since 10 months ( apowers313/webauthn-polyfill#1 ).
BTW, thank you for all your work on Mozilla Firefox :)
