 To be honest I've a mind to propose removing it entirely.
 It does a lot of processing just to figure out a few stats that a
 custom logformat and log processor could do better.

  The only reason it has not already been proposed for complete removal
 is that 3.2+ may need to use the Via: part of the DB to optimize
 expect-100 handling.
