In this specific case, since we know complete information of the
corresponding RRset, the log message can (and should) be more
intuitive.

In some cases there may be no other reasonable alternatives (e.g. when
we use plain integers for some kind of keys and it's not easy to get
the associated readable information).  I personally think it's okay to
print the row values in such cases for debugging purposes.  But in
such cases we should describe what these mean in the longer version of
the log description.
