@dschuff: I'm gonna interpret that as "I'd prefer someone else to take a second look at the MCContext parts". (If I misinterpreted that and you're fine with merging as-is, could you trigger the merge? I don't have commit permissions).

Thank you for your review!

@MaskRay: Since you are part of `pr-subscribers-mc`, would you be an appropriate reviewer of the `MCContext` portion of this PR (or can you recommend someone else)?
