The thing is, customers/players generally don’t care. Just look at the annual incremental releases of games that continue to sell well. Sure, there is also a cohort of players who love the indie scene for its more grassroots or authentic approach to games. Both sides of that player spectrum would ultimately be happy with more quality content, but I agree with you that perhaps one side may be more averse to AI “assisted” game development.
I think the nuance here is for a fan of indie games, how much of the artwork has to be hand generated? What if the artist uses AI to help speed up tedious work like additional frames or animation? What the game is entirely coded in AI but hand drawn (or vice versa).
