So what? You can kill them with three lines in your filter if they
bother you. As can I. As can anyone who cares. And a ULA-C will be
even easier: just one line to suppress the whole mess.

Are you so insecure about ARIN's ability to satisfy IPv6 GUA users
that you think those users will do what it takes to pressure the
network operators into reliably carrying ULA as if it was GUA? You
shouldn't be. ARIN does fine.

Hell, if it's a concern, why not offer ULA based on the registrant's
agreement not to announce it into the public Internet routing tables
and give ARIN the right to fine registrants and if necessary revoke
the registration for any uncorrected leak that someone complains
