let it fracture, as long as they remain largely compatible that is not a problem, heck some moving away from compatibility is not a problem either
which probably means the 3pps should remain mostly compatible, that way there is a lot of stuff to use with their games
maybe controversial, but with AI art, that is not really a problem for one person 3pps, and it already wasn’t one with real artists for the larger 3pps
I am also not sure how important art really is, the Manual of the Planes on DMsG had none, and is selling pretty well from what I’ve heard
