I think, this is a good point. Maybe you should make a ticket for it.

When I am trying to fill in a hole, I look to the "relevant bindings" to show me what pieces I have available to use. Those pieces don't include contexts! Is there something fundamentally hard about adding this information? I'd only want instance information for type variables--providing it for concrete types would make too much noise. I'd also want information on equality constraints, of course.
