OTOH, what harm is done by including it?

Consider a multihomed entity with one PI block and nine PA blocks; they
consume anywhere from one to ten "routing slots" depending on how
aggressively various providers filter.  Knocking this down to one "routing
slot" both gives uniform routing across the entity's addresses and reduces
the amount of bookkeeping ARIN must do (after the renumbering is over).

Aggressive marketing of this policy (even without my change) will go a long
way towards cleaning up the swamp.
