The binary is called kpackagetool. Given the complications we've had with frameworks co-installability does it make sense to call it kpackagetool5?
The class name in kpackagetool/kpackagetool.cpp should probably be renamed Documentation at the top of PackageLoader should avoid saying Plasma quite so much commented line at 773 of package.cpp looks concerning. I think it is just dead code. Installation command of plasmoids.knsrc are wrong (in fact they're wrong for current plasmapkg) Should kpackage even be providing this file? I think it should be with the plasmoid definition. IMHO PackageJob probably shouldn't set a parent to the packagestructure. Otherwise if you create a PackageStructure on the stack then call install/uninstall it will delete the job before it's finished. There's a Qt5 TODO on PackageJobThread::removeFolder
