     - when dirprot mode is used, the protected constructors are

     - the protected default constructor is always needed.

     - if dirprot mode is not used, the protected constructors will be

       - there is no any public constructor in the class, and
       - there is no protected default constructor

       In that case, all the declared protected constructors are
       needed since we don't know which one to pick up.

    Note: given all the complications here, I am always in favor to
