The Akonadi RSS resources (still lingering in some work branch, I assume?) and some plasmoids were also using it.

As for the dependencies: The KIO dependency is used only by a single class, “DataRetriever”, which is a rather thin wrapper around KIO::get to download the feed file.
The actual parser only requires KCodecs from KF. So I wonder if it would make sense to either drop the retriever classes completely, split them into another library (too tiny I guess), or make them optional in the build.
