In both cases, I included those things just because they were options  
in ANN, rather than any real need on my part.

The things that I found important (and lacking in some of the other  
many kd_tree implementations) were the ability to select an arbitrary  
number of nearest neighbors returned and specifying a max search radius.

I can see that having a choice of splitting rules may be handy for  
unusual point distributions, but I have always used this on fairly  
regularly spaced data.
