I have been following it quite closely, actually.Clearly you haven't been following the ppml mailing list. As I have already suggested on that list, ARIN could publish an authoritative directory of all unallocated IP address space at the largest aggregate level in a form that makes it easy for network operators to incorporate into their martian filters.
Why would ARIN specifically provide such a list? ARIN is not responsible for the unallocated space, and there is more in the world than just ARIN. There are liability issues with that, not to mention the fact that it is more an IANA function (if for the sake of argument someone would implement the list).
I guess monitoring NANOG or some other mailing list for announcements is somehow a lot more work. Oh well.And no, I'm not suggested that anyone connect their productions routers directly to an ARIN BGP feed. Smaller network operators will probably find such a direct BGP feed to be convenient but I expect all the larger network operators to use the BGP feed as a way of monitoring for changes which would be reviewed by some clueful operator before building the filters. That should not be a problem assuming that ARIN issues addresses every weekday.
