initially i was thinking we shouldn't accept people putting __json into derivations at all, but I'm not so sure now. i think that has possible valid use cases like wanting to serialize it in another process and avoid a round trip, perhaps, but we could certainly just outright reject derivations with bad __json as invalid at the daemon, assuming that uh we actually have any checks on those and they're not just like, sent over as bytes as it currently stands.
