+ * + keys that have a group width >= the old width but < the new width
+ * might have to be enlarged.
+ * If the key type decreased in size:
+ * - keys that have a group width > the old width don't have to be
+ * resized (because they must have some other wider type associated
+ * with some group).
+ * + keys that have a group width == the old width might have to be
