I think it would be good if the WKD draft would be updated to clarify
that a client should never answer to any 401 authentication requests
from the server.

Is this okay:

  A client MUST not accept a HTTP authentication challenge (HTTP code

You should capitalize this as "MUST NOT" (and not "MUST not").

  401) because the information in the Web Key Directory is public and
  needs no authentication.  Allowing an authentication challenge has the
  problem to easily confuse a user with a password prompt and tricking
  him into falsely entering the passphrase used to protect his private
  key or to login to his mail provider.
