There probably needs to be more consideration intertwined with things like #5576. When we move forward on that we should take this snapshotting into account.

I think there's enough here to move forward though. Especially since the hard part of this is the snapshot implementation itself which probably won't care much about how/where the lines are drawn for what a test is.
