I think that this is something that most of us go through. I know that I did. The device that you are addressing is called a reflex viewer (I believe that is true, I may be wrong).
Actually most of us discover that the upside down image in large format becomes an aid to composing better photographs. I think, from my experience, the reason for this is that it takes our "left brain" out of the equation by taking us to a place where we no longer name and identify that which is in the viewfinder and then we begin to pay attention to such things as "form", "negative and positive space", etc.
Perhaps some of the other LF users have a better command of language to describe what I am trying to explain and probably quite inadequately at that.
Good luck with your 'dorff. Good cameras.
