You can produce categories in the Tycho build and mirror these categories into a multi-version repository (if this is your use case). Categories have synthetic IDs, so there can be more than one IU with the same category label. If labels match, they are merged in the p2 IU.

The p2 tooling has mostly been developed to retrofit the build results of non-p2 aware build systems with p2 metadata. With Tycho, you therefore should not need these tools.

I understand that the category publisher is in fact something you may want to call outside the build. The FeaturesAndBundlesPublisher is rather a hack and should be deleted.
