Okay, well, our method for testing RPC compatibility is grenade
multinode, so we'd need a multinode job that does the skip level
piece. I could try poking at that to see, but again, I think it's asking
a lot from the projects to make that leap right away. If I'm wrong about
that, then we could surely explore that route.
