Some of the functionality relies on screen resolution to be deterministic, but I'm sure that can be creatively worked around. The real challenge is in the integration testing. With the current design the Package classes are in libplasma, the QML interfaces are in libplasmaquick, the configuration glue is partly in the image plugin and partly in plasmashell, finding the preferred image file is partly in the wallpaper package and partly in the image plugin, some of the image wallpaper logic is in QML some is in C++ in the image plugin ... these breakages are more from integration points than unit functionality.

yep, it is fixed in master, but would also need a backport to 5.1 branch

This means each plugin using Wallpaper/Images will need to figure out which image to use on their own. This is still better than not having access to the package definition at all, but I imagine other plugins will want similar functionality. A bridge to cross once reached?
