I think we could also turn on waves for this! Just APP=S2S -> S2SW. ICs should be there. I didn't turn it on because there was no point w/out the gfs part.

This looks great to me assuming it runs out of the box now!

Tagging @guillaumevernieres so at minimum he's aware S2SW got turned on as we should probably add it in some test like this, but if he'd prefer a different one we can do that instead.
