Comment 5 for bug 1877038

I'm busy elsewhere at present; I keep hoping I'll have some free time to work on WebAuthn soonish, but there's nothing definitive planned. Realistically, I have to rework the UX before I can really integrate the CTAP2 branch of `authenticator-rs` properly (since I need to do things like solicit PINs) and what passes for a WebAuthn UX today is currently broken anyway (Bug 1573190, Bug 1540309, Bug 1579927). So I need to learn how to do UX design as a practical prereq, which makes it harder to just casually work on.
