All I can say is that I'm not convinced.

My main objective is to keep the language's expressivity as it would
appear to a policy author (or human reader) in line with the
expressivity that it will really have.  A broad "deny" statement in
the language that doesn't really have any effect because the policy
is only evaluated in certain conditions is somethig else, and lends
itself to scope creep of the language.

I wonder if anybody else here wants to chime in on this.
