I get the feeling you really enjoy hinting at stuff & watching people whirr around like blind ants looking for crumbs :P
I'll say that the whole thing was designed with people coming together and exchanging information in mind. Not all of the "secrets" are mechanical things you can unlock, many of them are just little details that come together to reveal things. Sometimes you really just have to play detective, and try to be more astute than P himself was. So I'd say that decompiling the game won't necessarily show you all the fun things.
(It would show you just how many little variations we add all over the place to account for details though.)
I'll also say that we thought that having a Wiki would be good to make this process less chaotic and more accessible. Maybe people who crack what's going on will go there and throw their interpretations.
