   As an implementor, I would prefer not
   to be committed to keeping around arity information for every
   procedure.

I can't imagine how one could create an implementation in which the arity
information is not already present in some form for procedures that are passed
as arguments.  Similarly, implicit continuations had better know something
about the number of values on which they intend to operate.  Retrieving the
arity information may require some bit twiddling, but I suspect that the needed
information is always present in some form.
