Agreed, and this is the case.

Also agreed.

Reason #2 is the difficulty, whereas ARIN staff has to effectively make a 
judgement of the "compelling" criteria based on 3 illustrative examples.  
I recommend that the policy be so that there is a clear technical definition 
of "discrete network" is added to the policy, and further that any organization 
which has multiple "discrete networks" would qualify for use of the policy, 
regardless of the compelling or otherwise reasoning behind their architectural
