Without this macro, if any signals or slots were attempted to be used, they wouldn't work; neither would various other features of the Qt meta-object system. This can also lead to weird behavior in other circumstances. Qt's documentation specifically states: "Therefore, we strongly recommend that all subclasses of QObject use the Q_OBJECT macro regardless of whether or not they actually use signals, slots, and properties." on its page for "The Meta-Object System", which can be seen here: https://doc.qt.io/qt-5/metaobjects.html Let's opt for "always do the right thing", and keep the code extensible for the future and not have random things blow up on us.
