As I understand it, it depends on the details. Was the "update" a
transfer to a different organization than the original registrant? If
so then the new org signed an RSA to get it and is subject to the
contractual rules about fraud. That's one of the more or less settled
issues -- can't transfer the resources as legacy addresses. The
process of transferring them ends the legacy status. For the most
part, even the legacy registrants support this one.
Was it just a POC update? If so, you can update the POC back to
correct values with documentation. And really it's your own fault.
Granted email-auth was never stellar but if you kept your POC up to
date (like you agreed to do when you submitted the form to the NIC way
back when) then no one snuck the addresses out from under you.
At the end of the day, though, you don't rely on policy. That's part
of the bargain: policy doesn't touch you, for good or for ill. If you
want to be able to rely on policy, you sign the RSA or LRSA and accept
the strings that come with it.

The two issues are interrelated. ISPs get real leery about announcing
addresses whose registration doesn't match a the customer with which
they're dealing. Makes transfers without ARIN's blessing quite hard.
And ARIN only accepts transfers when the recipient is under a full
RSA, ending the legacy status of the transferred addresses. So yeah, I
can hand my legacy block to my buddy Joe and write him a letter of
authorization for an ISP to route them, but he can't get ARIN to
transfer them to someone else (he's not the official registrant) and
every time he wants to route them he's going to get grief because,
again, he's not the official registrant.
Really puts a damper on the whole transfer-outside-the-RIR plan. If I
was buying addresses from someone, I'd far prefer to accept the RSA
than deal with the fact that the addresses officially remain
registered to someone else. They're not really mine until they're
registered to me and I'm not going to pay you to keep the addresses
registered to you.
One key point is this: there's a vast amount of institutional
knowledge in ARIN's process for dealing with legacy registrants,
techniques and approaches built up as a result of dealing with real
situations over a decade and a half. You won't be able to capture it
in 5 or 10 paragraphs of policy text; you'll only take a flexible,
workable process and make it more rigid. The most it's healthy to do
here is tweak it a little and even then only if there's situations you
can point to where ARIN obviously did the wrong thing and has vowed to
do so again next time.
