The test only checks direct derivation from QObject. If you don't need any
of the Meta Object features (properties, signals, slots, enums, className,
qobject_cast, the meta object itself, etc.) why are you deriving from
QObject in the first place? :-)
QObjects are heavy: if you don't need any of those features, you shouldn't
derive from it.
Arguably, there might be a reason to derive in the QObject hierarchy
without including a Q_OBJECT macro, for instance to access a protected
member function, etc. But I don't believe it exists for direct QObject
