Generally (and slightly inaccurately) speaking, D follows the 
Java model for inheritance rather than the C++ one, where base 
class protection attributes simply do not exist.

Besides that, I'm not quite sure what privately inheriting an 
interface would buy you – there would be no implementation to 
inherit anyway (except for final interface methods, but I doubt a 
valid use case for this would be easy to find)?
