I have been following it quite closely, actually.

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.
