  But he tried to create new specification. What we need is to update existing one to reflect all the changes...

  Currently it is implemented in `statusnotifieritemsource.cpp`, it reconfigures KIconLoder to use themePath as additional icon location. 
  The best would be to have a similar implementation in `PlasmaCore.IconItem`, but this is a lot to change. `IconItem` is using global instance only `KIconLoader::global()`, while `StatusNotifierItemSource` has custom one (when needed) and fallbacks to the global one (`StatusNotifierItemSource::iconLoader()`).
