All correct.

You have the flawed assumption that everyone who uses RFC1918 space today 
will want/need ULA-C in the future.  The vast majority of folks will be fine 
with ULA-L (or PA) space, and the target market for ULA-C is identical to 
the target market for PIv6.  It will be the same number of orgs regardless 
of which type of space they request, so the debate comes down to why we want 
to put orgs on ULA-C space instead of just giving them PI space.  If they're 
truly going to use it privately, they won't consume routing slots in the 
DFZ, and if they aren't they'll be using PIv6 anyways and won't have a need 
for ULA-C.

I object to making orgs second-class IPv6 citizens under the guise of 
"private" addresses, and there is significant risk that ULA-C will end up 
not being "private" because there will be a set of ISPs that agree to route 
the space for a fee.  If that set grows to critical mass, ULA-C will be no 
different than PIv6 anyways.
