Unite is a bit different because using certain moves also ties into playstyle and there are major and minor balance changes going on frequently (like the Gengar Nerf and the Charizard Buff) that could change the way movesets can useful. I'm not saying that it is useless, either; for example, someone could write how to use Charizard to Attack and score, farm energy better, and or defend better, and which area you'd want to focus on also tie into and influence moveset decisions.
If something like this is made, however, due to the changing meta and introduction of new mons and balance changes, movesets may become obsolete or inaccurate pretty quickly, so that might be a pain to moderate/maintain. :P
