And actually, this text is all wrong. Let's fix it!  We can remove the bullet list completely and replace the text with the following.  There's really only one reason (not three): Package Restore.  In fact, dependency resolution will not resolve to unlisted packages.

Unlisting the package will keep people from finding it by searching the gallery and it will prevent the package from being discovered during dependency resolution.  The package is still available for [NuGet Package Restore](http://docs.nuget.org/docs/reference/package-restore) so that existing projects using the package don't become broken.
