I don?t recall that ever being proposed.

A protected variable can effectively have two identifiers using equivalence.  Currently we allow one to be public and the other private. 

Perhaps more useful: Suppose X is protected and public in module A, but in module B that uses A we don?t want X to be outwardly visible, so it is made private in B.   I don?t see a good reason to prohibit that.

One hopes all processors do that.
