When I made xwiki-store-filesystem-attachments, I made a mistake, I put the files which directly interface with the old core into the com.xpn.xwiki package. I realize it was a mistake not to ask about it and now I would like to correct it. This is an API break because these classes not under an /internal/ dir and are considered by clirr to be API. Since this implements interfaces which are defined in the old core, bridging is obviously impossible I would like to indicate somehow that those classes deal directly with old core and thus will be removed with it when the time comes. A) replace com.xpn.xwiki with org.xwiki.store.internal.legacy this will show that they are essentially with legacy code. B) replace com.xpn.xwiki with org.xwiki.store.filesystem.internal this will mix all of the implementations of oldcore interfaces with classes which provide services to them. Any other ideas?
