Several editors have adopted the habit of adding this information, together with the DiscID in the annotation field, as for example in this release:
If you like, you may also add that information to the edit note, instead of the annotation field. Bottom line is that the more information you document, the easier it becomes to weed out the incorrectly linked DiscIDs from those burdened release entries.
