To be fair DAZ has a similar problem with assets being reused. This problem was bound to be worse with AI cause while there are countless models out there to choose from the reality is most base models are minimum several times the size of the average RenPy/RPGM game and experimenting with them to find the right prompts, compatible loras to get the details you want, etc... takes anywhere from hours to weeks while with DAZ you always know what a model will look like when you download it but there's a limited set of free content.
