That's where I am wondering.  Using the Daniel's code:

  module M
    class_extension do
      def foo
      end
    end
  end
  module M2
    include M
  end
  class C
    include M2
  end

  M.foo   # => NoMethodError
  M2.foo  # => Error? (should it affect modules?)
  C.foo   # => Error? (should class_extension be propagated?)

If 'class_extension' affects modules as well, do you think of any
more generic name, in place of "class" extension?
