How about if the routing-wg does the right thing and leave the RA and
InterNIC to either cooperate with each other or the RA to ftp and fill
in inet-nums or disable the feature (hopefully not the latter).

I would not expect to see the same address space allocated by more
than one registry.  All registries would have a top level 0/0 route
object which prevents registry of bogons.  RIPE would have a hierarchy
under 0/0 and the RA would have a hierarchy tracking InterNIC assigned
addresses.  I would not expect the two to overlap, therefore there is
no real coordination problem beyond initial setup or new blocks
allocated to a registry.
