My point is that flx scoring is usually based on the idea that the
candidate does match using flx matching, whereas that might not be the
case is the matching was done some other way.  So the scoring result can
be completely meaningless (or it could even signal an error).

IOW matching and scoring can be intimately linked because the scoring is
based on *how* the candidate matched the input.
