You kind of answered this yourself in your original post.
There wouldn't be a point.
public: the class is available outside of the package
package: the class is only availalbe within the package.
If you think about it, private, package and protected would all achieve the same goal - restricting access to the class to within the same package. Since packages can't be "inherited", there is no use for protected. And the default access modifier (package) does not allow external access, so private is made redundant.
I would gather that there are only two (public/package) in order to keep it as simple as possible.
