I think it does.

This function is very useful for maintenance, database synchronisation, error
detection etc. as I mentioned earlier. I agree that this function should not
be a "standard" function, i.e., the normal query should not report the reverse
references, as a name server may be used by thousands of domains and this
would increase processing time and message size. It should be done either as
an option or as a separate request.

Yes, but let us distinguish the directions of the references (compare to the
directions of the arrows in the example). Normal queries would only report
references that point away. On special request, also those references are
reported that point to the object itself.

This was for demonstration purposes only. CORE has the ability to associate a
contact in its SRS, but the feature is rarely used AFAIK. So for me, you can
keep the can closed ;-)
