That would cost a counter in every state blob,
which wouldn't matter on DNS servers with small state tables and generally
where keeping log files and counting lines there lines is feasible,
but might where on busy DNS servers.

Since there are overall RRL statistics, I propose not adding those counters
unless there is a hue and cry.
