Jon’s fix helped with the issue somewhat. When I use the new dependency graph as he suggested, I only have to click once to get the wing spline to settle in at the new position. Without the new dependency graph, I grab the wing, click to reposition it, no change. I have to grab it again and then right click out to get it to settle. (I use Blender 2.78, but I tried it on 2.79 fresh download too, same behavior.)
Either way, it won’t update live, even with the new dependency graph turned on. Feel free to look at the Blend file still, but I think this is as good as I can get it. I’ve moved on to rigging the tail, which won’t bend smoothly with the new Bendy Bones options, but I can probably find a workaround.
