ULA-C uses a different prefix from ULA-L, so nobody using ULA-C (if it
passes and is implemented) should ever collide with anyone people using
ULA-L. The only possible collision is between two orgs using ULA-L, and the
RFC covers the odds of that happening.
OTOH, one participant in this discussion has already created a voluntary
system where folks who want to register ULA-L prefixes can do so, and there
will be zero collisions between participants in that system. That gets all
of the supposed benefits of ULA-C without any additional work by the IETF,
IANA, or RIRs and costs no money. Bingo, ULA-C is now even more pointless
than it already was.
