When you demo, you show a scenario. You know how to wow the public and you consider what is of interest and makes people anticipate the moment when they can get their hands on the code. The moment of truth, when the software is not used within a scenario, where the article that is edited is no longer called "elephant", but can be any article.
Consequently, it is no longer convenient to hard code "elephant" because people might want to write an article called "tsunami" or "spring tide" when they think that "wave" is a bit tame. There are five such hard coded gotchas. In stead of a predetermined solution, we want the same flexibility as in all Wikis; you determine the name of the article.
So our demoes are rigged, but we are removing the rigging and make it what you see is what you get.
