Hello, I'm one of the LXQt developers so I can answer part of your questions.

Libqtxdg uses Qt private headers to woakround bugs in QIconTheme and QIcon. Lxqt-plugin uses Qt private qpa headers to support customized themes and make some desktop settings work correctly. Our LXQt file manager pcmanfm-qt will be using Qt private headers qdnd_p.h for workaround a regression bug of Qt 5.5 which breaks DND.
