ADDITIONAL INFORMATION
Nested eventloops are the devil. I would suggest to deprecate ::exec and drop
it with kf6 entirely. Porting away from exec shouldn't be too much of a
challenge, the few apps I've looked at mostly seem to reload their state when
the dialog closes, that can easily be done in a lambda slot.
