True enough, but are there any providers currently that filter /24's from the old Class C space that /24's were assigned directly from? I realize that if proposal 2002-3 does get passed but everyone filters those prefixes then it will be a completely worthless proposal, and even worse than using PA space. It seems to me that proposal 2002-3 could enable providers to filter more efficiently however. They could accept the long prefixes out of the micro-assignment block, while filtering out all the garbage /24's in the other space caused by people needlessly announcing every /24 out of their large aggregate.

Forrest,
Even if ARIN passes this policy that will not make any provider change their filtering policy. It is true that many providers do use the ARIN allocation sizes to create their filtering rules but the two are not inherently linked. Any ASN can choose the filter on what ever rule set they choose.
