the discussion is whether it's appropriate for the RIPE NCC to continue
to publish route objects for this prefix, which is a different
discussion to the announcements in the dfz.

The route objects are documentation of policy.  If the prefix isn't
legitimate according to IANA or RIR allocations / assignments (and in
this case, it definitely isn't), then the route object shouldn't be in
the IRRDB.

There's nothing stopping operators from continuing to announce the
prefix.  It would be better if it were left to die, but this is
ultimately a choice of each individual operator.

The same argument applies to the route objects for 2002::/16.
