The issue is that if Feature F includes bundle B, then source feature F.source will include bundle B.source. So if we want to rely on Tycho automation for source features, we have to ensure you can get a source Bundle B.source for any bundle B. Otherwise, source feature creation will fail.Mistria - does tycho source feature automatically exclude plugins that doesn't have sources or does it enforce every plugin listed in the original feature to have sources (even if just empty)
