Not necessarily true. As was pointed out in the opposition to my prop. 139
there are several instances of LIRs without circuit-level relationships.

I can point to more than 100,000 users without a billing relationship that
have address assignments from at least one provider, so, I don't think
that is as unusual as you claim. Some of these users have just over 18
quintillion addresses, while others have 66,537 times that much or
even more.

Arguably if they were not aware, then, they were not "using" their
resources. However, if they have followed policy and kept their
POCs up to date, the POCs would have been notified well
before the "immediate" reclamation which usually takes at least
6 months.
