I'd say the main reason they didn't move forward with play maker is because they didn't want people to be required to buy it (or pirate it in most cases) just to develop content for vrchat, which makes sense. Developing their own solution also makes it easier to manage network behavior.
I would argue a lot of people who import avatars to vrchat have absolutely no idea what they are doing in blender/unity, and thats why you have people running around with dozens of skinned meshes with poly counts in the high 6 figure range. Regardless, it is in their interest to make their platform easier to use for content creators, because vrchat is nothing without its content creators. We'll just get idiots who make stuff with everything in the update() loop like yandere sim.
