Same, no implementation outside Chrome/Edge.

I noticed that the test wasn't looking at getTransports but it is
supported in Chrome/Edge. I checked that one manually as well and
arrived to the same conclusion.

We can add a WPT for getTransports if useful.

Also found no progress from Firefox or WebKit on getTransports:<><>

Are we aware of implementations?

Chrome implements enterprise attestation as of Chrome 90, but I'm not aware of any publicly obtainable authenticators that support it.

Apple's attestation is implemented by iOS and macOS.

It looks like the results from won't be enough of a story so we
need more information to complete the implementation experience [1]. It
could be that Google and Edge don't share much of the code anyway for
example. Or that no difficulties are foreseen by other implementors and
they just didn't get around those functions.

I don't know how much Edge's implementation differs from Chrome: I only know Chrome's implementation I'm afraid.
