Yeah, seriously not even remotely worth hoping that Nintendo would do such a thing.
I mean it's really an issue of control. Nintendo wants to control the way their games are experienced and the way their systems operate so that they can guarantee a particular customer and 3rd-party developer experience that they feel best represents their company.
Think of it this way:
Let's say that you have just finished developing some sort of epic masterpiece of a web-game. I mean this thing is a technical triumph toward which you have spent most of your time and energy over the last one to two years creating. As far as you are concerned, this game is a work of art.
Now imagine that a week or two later someone has made a number of easy graphic and text hacks to your work of art, and has re-released it under the name "**** Racer 5." Not only that, but they have still maintained your name on the development credits. So, now, instead of being known for making what might have been considered a gaming classic, you are instead known to many people as the guy who developed a game ostensibly about racing genetalia.
Personally, I'd be a little pissed.
Now this is in no way attempting to discredit or insult any of the incredibly remarkable work that has been done by the absolutely brilliant developers in this or any other gaming community. Instead, this is simply an attempt to express the sort of misrepresentation that can occur when the audience is given unlimited freedom (I mean, I'm sure we've all seen the people online in one game or another who simply find it impossible to be anything other than incredibly crass), and to illustrate how a developer might feel about edits to their work.
As with any post that I make, if you find this to be stupid or in anyway particularly disagreeable, please feel free to ignore it.
