I'm afraid I disagree. I'd prefer to see it encouraged to keep the traversal 
policy simple and consistent (which probably means non-configurable: think the 
why-did-they-do-that--because-they-could syndrome of things like Plone) and in 
so doing mean that people who want to use paths don't have to end up 
understanding how the underlying traversal components work because they all work 
differently...

I can see your point of view, but I'm not convinced myself yet :-S

cheers,
