`sourceName` was not actually unused; this makes compilation fail with certain combinations of flatpak and appstream: ``` /home/nate/kde/src/discover/libdiscover/backends/FlatpakBackend/FlatpakBackend.cpp: In member function ‘void FlatpakBackend::createPool(QSharedPointer<FlatpakSource>)’: /home/nate/kde/src/discover/libdiscover/backends/FlatpakBackend/FlatpakBackend.cpp:1029:101: error: ‘sourceName’ was not declared in this scope; did you mean ‘sources’? 1029 | const QString subdir = flatpak_installation_get_id(source->installation()) + QLatin1Char('/') + sourceName; | ^~~~~~~~~~ | sources ``` I guess you didn't hit this because you have newer AppStream stuff.
