Is there a way to generate compile-time warnings for _enum values_?

Here are some existing flags that were missed during the Qt 6.0 cull:
* Code comments -- QLocale::ImperialSystem is commented as "// Qt 4
compatibility" [1]
* QDoc free-form text -- QLocale::Uigur is documented as "Obsolete,
please use Uyghur" [2]
* QDoc commands -- Qt::Desktop (from Qt::WindowType) is hidden with
the "\omitvalue" command [3] (although a QDoc bug made it partially
visible still [4])
