I've had Lightroom (Premium) for 2 years now and just one of the things I would love to add to my editing is where you could add shadows, exposure, highlights etc on a single thing. I would call it a "Subject Chooser" it would consist of the same code/tool for subject detecting but with my suggestion, you can select a single object, person or part. For example, I want to add shadows to a specific person so within the "Subject Chooser" feature I can press "Manual Chooser" so it does another scan and finds it and only highlights/masks that thing. A photo below is an example of what I would use my suggestion for, the person in the middle is a bit under exposed and I would love some more shadows. That's where I could use that feature.
Hope you consider my idea,
