Why would you see that as a defect ? Will your bundle work if you don't have the namespace handler present ? I doubt it will ;-) So your bundle actually requires those services to be present, even if you as a user don't really know it. Actually, you'll also notice that the bundle also import the org.osgi.service.blueprint package, even if your bundle does not actually require it. Would there be a way to express the fact that the bundle needs to be extended by blueprint, this should also be in the manifest.
