I think I understand what you're getting at. The complexity of these liceneses seem like a big trap for young players.. I see CC-BY-4.0, I know pretty well what I can and can't do with that content.. if I see OGL (or presumably the "ORC" or whatever else) and its immediately unclear to me what I can do with what part of a textual description of a spell, for but once example.
I think as a software developer, its easier for me to draw a circle around mechanics vs content/flavor/"Product Identity" than most, but I would love a licnese that makes clear that the mechanics (data structures / formulas) are free and can't be "captured" by closed licensing, but license the flavor any way you choose as a publisher, and leave the decision to me to decide whether or not I purchase it considering the work and the terms of its purchase.
