Hank - 

Yes, ARIN could add a statement to that effect to the registration services agreement – note that the granting of rights to the address block in the registry is already present, so it’s really the addition of the grant of  "sole permission to announce that address block to the Internet” that would be added.

The problem with such a statement is that it is either: 1) meaningless, or 2) creates obligations on recipients that are not clearly stated. 

The reason why is that ISPs have the ability to configure their routers as they see fit, including deciding what routes they announce and what routes they accept.  If the community wants to infringe on this freedom, then we need to be very clear on that point. 

ARIN “granting permission” for an ISP to announce a particular address block doesn’t have any meaning (they already can announce anything they wish) unless it also implies that ARIN doesn’t grant one permission to announce other not-assigned address blocks _and_ that you agree that your unauthorized announcement would be some form of breach of the agreement.

In effect:. “Address Holder agrees to only route to the Internet its own address blocks, or those address blocks for which it has obtained permission of the registrant as listed in the Internet Number Registry System.”

Does the reformulation help clarify why the addition of that responsibility might be seen by some as rather significant?  If you actually intend it to be a meaningful change, then it should include the corresponding obligation in clear and uncertain terms.

It’s possible that such a change is reasonable if the community wishes, but absent a clear and unified expression of support, ARIN could not consider adding such obligations to registry customers.
