As you can see from the commit, no

No, I tried, it seems to work as expected:
==

Q_OBJECT
};
class

Note that inherits() / className() will not work as intended if the
subclass does not use Q_OBJECT. Only typeid() will tell you

Hi all!
A couple of days ago a bug was filed against a project of mine, which

which was introduced in Qt 5.15:
