I don't think you convinced "the company Nokia" - most of the company will not even read your bugreport or this mailing list. You might have convinced some Qt Creator devs though.

What does that have to do with any particular IDE?

Friend declarations get out of control even faster.
As with almost all programing concepts it's all about having guidelines for the concept's uses, so they don't get out of control.
That applies to the examples above too, both friend declarations and nested classes.
BTW, nested classes (and structs and enums in classes) are used at several places throughout Qt and Qt Creator, exactly for namespacing + encapsulation.
