`hide-zero-packages` never runs #4472

This is something we can prevent in the future, for every feature, inside features/index: isUserProfile.length === 0 && awaitDomReady === false -> throw Error

The length check means that the function is DOM-based; it would have to be repeated for each function in the include array.

But there are domReady safe detections (Those in meta tags).

I was thinking of allowing elementReady pageDetections (With no plan of how to implement)

Good point

This would mean copying the detections from GitHub-url-detection and replacing exists() with elementReady, I suppose, but I don't think I'd like that (because we have to update the selector in 2 places)
