Regarding it being a compiler, I can get behind that: no compiler artifacts in the repo, lol. edit: in fact I'm pretty sure if they were putting compiler-generated assembly into the repository, which is awful and you shouldn't do that, they would keep information what compiler shat them out.

I can see in some 5..10 years, deterministic coding tool that either converts specification to code or asks for clarification and then edits said specification to disambiguate. One way flow, generated artifacts kept out of the repos. That's not gonna even begin to happen until the bubble pops though.
