Ok, I understand. But if this is only about making it possible to keep
multiple SDKs at the same time, then I would use

"com.google.gwt.eclipse.sdkbundle.e35.feature.2.0" instead of
"com.google.gwt.eclipse.sdkbundle.e35.feature.2.0.0"

Or do people actually want to keep both "2.0.0" and "2.0.1" around?
