Yes, for learning purposes it would be great, I would take a look into it too.
There are a couple of users making own editors mainly for own purposes (including me), and it would be probably an easier access to some engine features, than making it alone, or asking stupid questions from the developer(s). So this way in my opinion 3DGS could finally profit from it, not only by correcting GED's errors.
