Richard - Hopefully, we don't need examples of compelling reasons if
a clear technical definition of "discrete networks" is added (as it 
would remove the requirement for judgement of "compelling reason")

[A] is a simple matter of fact, i.e. show networks with unique routing

[B] still requires judgement, i.e. explain why the networks must have 
unique routing policies in order for the networks to operate "correctly".  
It is clearer than present policy since it would have a clear definition
that equates discrete networks as networks with unique routing policies, 
but wouldn't eliminate the need for judging whether or not the use of 
those unique routing polices was truly necessary.

Using [A], if a definition of "Multiple Discrete Networks" is added to 
read: "Multiple networks are networks with unique routing policies",
then the criteria could be greatly simplified to simply show presence
of multiple discrete networks.

Note: I have no idea whether the community wants either change, 
but suggest you propose either one, should it better meet your 
needs.    Details on submitting a policy proposal are here:
