emlun has just submitted a new pull request for https://github.com/w3c/webauthn:
== Note that largeBlob requires discoverable key on CTAP authenticators ==
I did some interoperability tests with the `largeBlob` extension, and was confused because Chrome indicated "Your security key can't be used with this site" with `largeBlob: { support: "required" }` even though my security key should support it. It turned out to be because CTAP only supports the underlying extensions for discoverable keys. This is not a general requirement, but CTAP seems like an important enough class of authenticators to point this out.
