I suspect some do.  It will be interesting to hear from them.

Mine is little more than a swap function.  I think Bruce once said he had
replaced his Qsearch with a swap function with little effect.

The Qsearch (since it severely restricted what is considers) is full of errors
anyway.  Best thing is try both ways, since the impact probably depends on what
you do in your main search.
