Comment(by nickm):

 Also, this isn't just about #9001: decoupling and abstracting the path
 selection code would:
   * let researchers prototype new path selection algorithms more easily
   * make the path selection code more testable^*^, and make changes to
 that code testabe
   * make the path selection code easier to review
   * probably, make the path selection code less buggy

 Does anybody want to take a stab at figuring out what the API should look
 like here?  I can try to outline it in a week or two, if not.

 ^*^ Having 'testable' code helps, but since we need to make our
 refactoring itself tested, making the code testable is more of a long-term
 advantage than a short-term one.  (That is, in order to refactor to become
 easier to test, we must first write tests.)
