Why the small hole? There's plenty of space in the lid clearance hole to relieve air pressure. I don't think I've ever seen sufficient fluid in mine to need a drain hole. I don't think it would help, but I guess it wouldn't hurt.
I made my cut washer out of stainless so I didn't have to break a plated surface.

Thought the small hole was factory.
Mine not only has the small hole, too, but there also is a plastic socket. That comes first, then the washer (grooves facing down towards the plastic socket), then the nut. Apparently avoids scratching the reservoir lid.

Now this all makes sense. Thank you Graham and Konrad for posting the pictures.
