I know that that CartChunk support has been discussed here before (see for example, but my understanding is that it has never happened due to the need to maintain a stable ABI within the larger KDE project.

To be honest, if I end up still being in the maintainer's seat for a 2.0 release, I intend to remove, rather than add additional formats.  The problem with a lot of obscure formats is that they end up being dropped on TagLib, often with code in a questionable state, and then the maintainer ends up having to try to fix bugs for formats they've never even heard of and are not widely used (and more importantly, don't know the spec for at all -- meaning trivial bugfixes can mean a lot of reading in advance).

That said, removing said formats would come with finally fixing the file type resolver API so that third parties can easily add support for formats they're interested in.  Moving those formats out of TagLib would allow their maintenance status to vary independently of TagLib's.

Yes on API requirements, and honestly, no on a PR for those formats.
