It won't get tested by the bots because we don't have any default configurations with Chrome Home enabled.

Oh - I see. So there's no way around the fieldtrial.json error that we'll get when we move that experiment to beta+?

We can still add an entry. I guess maybe our Chrome Home tests will pick it up... All local builds will also start showing the labels when chrome home is enabled.
