Most models seem to be distributed by/for researchers and industry professionals. Stable Diffusion is state of the art technology, for example.
People who can't get the models to work by themselves given the source code aren't the target audience. There are other projects, though, that do distribute quick and easy scripts and tools to run these models.
Apple stepping in to get Stable Diffusion working on their platform is probably an attempt to get people to take their ML hardware more seriously. I read this more like "look, ma, no CUDA!" than "Mac users can easily use SD now". This module seemed to be designed so that the upstream SD code can easily be ported back to macOS without special tricks.
