If you know how to organize UI in GIMP, then you must have been annoyed by the reminder label “You can now drop dockable dialogs here.”
Hence, as complained by most of the GIMP users, the message will no longer be displayed in your empty workspace layout. While maintaining the flexibility to arrange the dialog on screen, the targeted dock area will be highlighted once you begin the drag operation.

The new feature added in the 2.10 milestone, which will feature in the next point release 2.10.16.
