Yes - I have to agree with this statement.

Would it make you feel more certain if the ULA-Cs were
self-generated by sites exactly as in (RFC4193, Section 3.2)
and then "registered" with a central authority that would
register the address as long as it is not a duplicate? I
don't think ('draft-ietf-ipv6-ula-central', Section 3.2)
currently says that, but it seems like it would result in
a scenario that is no worse than for RFC4193 yet with a
central authority accountable for certifying uniqueness.
That said, I would be astonished if this idea has not been
entertained and debated before.
