For myself, I'm in the sitaution where I have very little concern about the rules as a player - I'll play just about any system. In your analogy, I'm a very unpicky eater. I like all kinds of food, from all cuisines and cultures, and all I really want is a well prepared meal. And also, in real life when it comes to food, I'm also a very unpicky eater.

The problem is that my easy going eater preferences really aren't relevant because 80% of my RPG career, I've been the GM.
It is very relevant. In regards to D&D Next, WotC is the chef, and you are the picky eater.
