The important thing to take from my comments is that a necessary function is
determining when and how you can determine that there are no more interested
receivers in a set of VPN routes by property.  RD-ORF originally had this in
the context of RD.  This draft potentially widens the problem space.

I think you will find that it's difficult to do this. 

The RT-Constrain example mostly is there to provide a more tractable case
than your base case.
