Even if you had that representation, resolving merge conflicts would be a huge headache. Imagine resolving code conflicts by resolving things at the AST level.

Forget CAD, we don't even have a good way to version control images, something programmers work with every day, besides "use Git LFS and pretend an image is just a pointer".

edit: just saw GumTree mentioned above. Guess I have something to check out...

Of course not possible with images as a binary blob but it could be possible with a series of operations on a (vector) image ("event log").

This sounds extremely nice actually. The more semantically aware the version control system is, the more likely it can gracefully handle merge conflicts. A textual diff is a very low level transformation primitive; composing them doesn't guarantee very much at the higher level.
