I agree this is suboptimal as currently written. As I recall, the construction of "Let _userPresence_ be a Boolean value set to the inverse of _userVerification_" was done in order to [align WebAuthn with CTAP][1] and get the desired behaviour, but looking back now at the CTAP archives it seems like I might just have misinterpreted those CTAP consent collection steps as exclusive branches instead of sequential steps.

>I will suggest we change the WebAuthN spec to:
"Let _userPresence_ be a Boolean value set to the inverse of _userVerification_." => "Let _userPresence_ be true."

I support this suggestion, but I think we probably can't do this before L2.
