Definitely agree with your sentiment about the promise of Blender artists and developers collaborating to produce even better tools and solutions.
I wasn’t familiar with makehuman. So I just checked the website. It looks great! I would love to explore any collaboration opportunity.
As per my understanding, parameterizing an articulated model is far more complex than rigid bodies that I am proposing to modularize. My focus is on the models that are geometrically simple but are usually customized in terms of materials assigned to them or slight geometrical tweaking.
