Re: [webauthn] Privacy concerns with blacklist/whitelist

@kpaulh So essentially Chrome ignores this part of [§5.1.3][create].19 and [§5.1.4.1][get].17?

That should indeed make it impossible for the caller to see a difference between (1) timeout and (2) the credential is available, but the user denied consent to use it. It doesn't seem like this instruction would add much to the user experience either. So should we just delete it from the spec?
