Yea, I think the compression could be further done to basically make everything available right at the start. Looking at the SCORE code, feasible, but it would probably more of a problem to make a different mode, than just having it universal. (I can read code, but I'm not spending a lot of time on it)
So back to "Is this a good idea?" There's a lot of reasons not to spend the effort on this, and really just a couple for it. I get the impression that the devs do some stuff just to see if it can be done and some things are tests. (Blarf being a prototype of the Lab Minotaur for instance)
