This highlights why it is insane to restrict a resource to 'only for use
within the allocating region'.

And the 'flexibility' creates ambiguity, which in turn leads to conflict,
which in turn makes the proposed language unenforceable. Simplify and make
the requirement 'must justify existing global resource use against policy of
the RIR being asked'.
