And what about showing all of the terms that a field group may be attached to, or users, or options pages, forms, widgets, attachments and images?
If the developer did this he’d also need to deal with all the possible custom locations rules that people add.
Every post, user, attachment, widget (etc) would need to be queried and individually tested against the same location rule logic that’s used to display the groups on the correct edit page.
It’s not as simple as doing a single query to see where the field group will appear. That information is not stored anywhere.
