Routers would ship with the iana_reserved_block list of when they were

of black holes for newly allocated address spaces to the RIR's.
Exactly. (Unless "IANA reserved" != "unallocated" but IANA does call unallocated space "reserved".)

The cure will be far worse than the disease if routers would come with
pre-configured bogon lists.
Indeed. In fact, the whole bogon filtering thing is more harmful than useful.

If you do any bogon filtering at all then do it with some automatically
updating system like an BGP bogon feed from Cymru.
What exactly does this feed do for me? Wouldn't bogons be everything that isn't in the global routing table?
