It is not anysuch thing. All it means is that if YOU elect to use one
of those networks, it is YOUR responsibility to make sure that you do
not announce that network to the Internet. It imposes no requirements
on anyone else.
The IANA can ensure that the NSFNET will never accept those routes
through the PRDB mechanism.

Yes. Become involved with the IETF, and join the CIDR Deployment (was BGPD)
Working Group. Take the opportunitieis to submit comments upon Internet
Drafts before they become RFCs, not afterward.
