That's an excellent idea.  Have a generic default algorithm that
performs reasonably well in typical use cases, but also give the user
the power to choose a different algorithm if he knows that it would work
better with his particular use case.

Empowering the user -- over time I've come to learn that this is always
the best approach to API design.  It's one that has the best chance of
standing the test of time.  Fancy APIs that don't pay enough attention
to this principle tend to eventually fade into obscurity.
