These "fake 200s" affect metrics. We inflate our pageview numbers (however slightly) with these hits which cannot be pageviews as they have no content.
Many bots are hitting this one for example and using it as some kind of keep-alive: https://en.wikipedia.org/w/index.php?title=User%20:GoogleAnalitycsRoman6/google-api&action=history
