Feynman paths would basically correspond to points in spacetime configuration space, ie, histories, rather than points on plain ole position configuration space, wouldn’t it?
(Actually, summing over histories is basically one way of explaining WHY in GR things follow geodesics. Think of metric as being analogous to refractive index, affecting the “optical” path length, so you end up getting the same idea as principle of least action.)

Exactly.
