Is marking a change as WIP in Gerrit sufficient for this?
Well, we'd need to have a way to configure CI to not run in those circumstances (and make clear to users that that was happening). And then we'd need a way to manually trigger CI to run even on a draft patch. But if you think that's a reasonable requirement, yes.
