No, because Allow refers to the allowed methods of a particular resource
and the others refer to the capabilities of the application on the
server end of the client's immediate connection.  Therefore, Allow is
independent of the means of communication (the intermediaries involved),
whereas OPTIONS and Public refer to the capabilities of the currently
communicating neighbor.
