     1. offer QStringView, overload some functions taking QString with
     QStringView
 
-    2. like 1, but remove all overloads of functions taking QStringRef,
-    leaving only the function taking QStringView.  Do this only where
-    QStringRef overloads tradionally existed.
+    2. Obsolete: QStringRef and its overloads have been removed.
 
     3. like 2, but replace functions taking QString, too.
