I agree that would be cleaner and made the change. That’s what I started with but that’d leave ModuleTarget attribute in the class file.

There are a couple of places that use the old name in method names and maybe we should rename those too. One other rename is the plugin has "PackagesAttribute" when it should be "ModulePackages" attribute.

I fixed up a few places in ModuleInfoExtender as well.
