Provide params or routeParams to getIndexRoute

[ryancole]

I'm using dynamic routing and have a scenario where I'd like to use a particular react component depending on a route param. So for example, if I've got a route like below ...

/:slug

I've like to be able to look at that slug and if it's A then use component A, or if it's B use component B.

Right now, getIndexRoute receives the location param, which does have the current path ... as a string, though. There exists the params and routeParams props that get passed into route components. Could getIndexRoute receive these too, so that we can make more precise logic around the route params?
