Nice theory, but in practice it's a little ickier than you make it sound.
Consider most people on this list deal with networks (not just single
sites) spanning multiple states or countries.  Not everyone can afford to
build both a backbone and a separate management WAN.  Putting management
in 1918 space is ok at one location, but gets tricky on a large network.
Do we then also buy/maintain VPN hardware to connect all the various 1918
management networks to the NOC?

This actually might be an interesting use for MPLS VPN for those networks
where all the core gear supports it, but a totally separate management WAN
is cost prohibitive.
