Uh, neither of those reasons undermines the solution others have
proposed: use PI space.  You can always just not announce some part (or
all) of your space.  That would make it private.

ULA-C sounds to me like a request to the guys who spin silicon to help
people keep from screwing up their router configs.  If someone can't
manage to filter their BGP such that they keep some (or all) of their
space private, I don't see why Cisco, Juniper, et al., need to do
that for them.
