Interesting, thanks for elaborating!

I have had similar thoughts: Having a low-level representation that only makes sure that a geometric object you reference actually exists (and does other low-level validations), then have a wrapper around that, that provides higher-level operations and makes sure your model is also manifold.

This isn't thought out yet, just some stuff I've pondered. Thanks for providing more input to my thought process!
