Support/Yes.

I will add that it would be nice to briefly consider the operational implications of "accidentally" crossing route-reflector planes in a future version of this document.  Specifically, in the case of co-located route-reflector planes on /existing/ RR's, in my understanding the only thing keeping the first/primary plane separate from the secondary/backup plane is use of separate Loopback addresses on the iBGP sessions.  Thus, it is quite likely that an operator may get those mixed up when establishing iBGP session's for the first & second control planes.  A potentially simple, but effective, existing method to keep them separate is for operators to use different TCP MD5 passwords on iBGP sessions for the first, second, third, etc. sessions in order to ensure consistency of the control plane sessions.  This should still keep things in the realm of using existing, widely deployed tools with no modifications to existing code.  FWIW, I would be happy to contribute text if the authors and/or WG agree with the above approach.
