Something like KIO::CapabilityJob *job = KIO::capability(Move, url1, url2); connect; and in the slot, enable/disable the action accordingly. By default this would just use the information from the .protocol files, but in addition a new SlaveBase method (fake-virtual until KF6, using virtual_hook) would allow slaves to answer the query with more precision, depending on the actual URLs. What do you think?

Yes, now I can rename from dolphin. There is a (malformed url) error if I try to restore a file that I just renamed, but it does work after if I reload the view. Anyway I think I can discard this patch now!
