Exporting - the wrong default?

I don't think public ever meant "public to the world". In Java 1->8 it
means "visible to those who can see the containing scope". If you
declare a public inner class in a private (or package-private) class,
then those who cannot access the outer type also cannot access the
public inner class.
So no, "public" never meant "visible to everyone", it was always about
On the other hand, for toplevel types, the scope had always been the
package, and packages were public by default. Now that default changes
to private, but notice that even here, a package is only private outside
its scope (the module). Other packages in the same scope (module) will
be able to access it.
So for me it's always been about exporting from the current scope.
