It would usually be the packagestructure setting it, in initPackage(), so setFallbackPackage follows the same pattern as addFileDefinition(), setRequired() and the likes.

so, for the packages of type Plasma/LookAndFeel it would be org.kde.breeze.desktop
for packages of types Plasma/Shell, it would be org.kde.desktop

even tough at some point it will probably have to be something more complicated, like the default lookandfeel one depending from  the current shell, if ever needed, will be feasible.

as "package that has fallback" but yeah i can flip the names if more clear, since the api calls it the other way around

yeah, oddly does compiles fine.
may have to get even if ugly a const_cast instead there
