Is it possible to improve Access Control?

Hey guys I think a lot of developers will be happy :) If in Access Control also will be like "extensionprivate"

Wait!, what does it mean "extensionprivate" :)

Let me describe

Currently we have

Open access Internal access File-private access Private access

also I'm suggesting to add Extension private

This is cool because you can add a "extension-private" property that will only be visible in the extension.

Is it possible to improve Access Control?
