    It's not bad. I don't fully understand the code in `CountMatchAlgorithm` 
(the only place where the boolean flag makes a difference), but it seems like 
it only reorders the match traversals, possibly to optimize memory consumption 
and/or processing time.


> Remove deprecated TraversalSource.Builder and TraversalEngine.
