[Interest] Are slots even needed these days?

[Constantin Makshin]

Yes, but, as you said, it's just a hack meant to circumvent C++'s member
visibility system. A rather ugly hack easily detectable by simply grepping
the source code (in a pre-commit hook, for example -- presence of
QMetaObject::invokeMethod() calls outside some parts of Qt itself may be a
good sign that somebody wants to do something weird).
Direct method call, on the other hand, is less likely to both cause
suspicion in anyone looking at the code and to be found by automatic tools.
