I'm not sure if we want to change this interface and this feels a little
hacky to me. It seems like `planLater` might actually be the problem. In an
earlier prototype we actually use a node that indicated "planLater" and looped
it back through the planner instead of doing it all eagerly. This let us do
plan space exploration, but I'd have to spend some time thinking about how
exactly that could work.
