Right - and Solr attempts to preserve external interfaces (HTTP apis
and query languages) even across major versions.
It could be argued that this is a regression - a loss of the ability
to use higher edit distances.
I'd support adding a fallback to SlowFuzzyQuery when the edit distance
turns out to be > 2.  I'd even argue that it should do it by default
to retain the old behavior.  Basically from the user perspective it
would look like edit distances of <= 2 were sped up.
