Today a user handled me a rar archive (from a windows machine) with a Cargo package. When I extracted it on my linux machine, I've noticed that cargo build always rebuilds the project, instead of doing zero builds. Looks like the problem is that extracted files miss mtimes, so we always rebulid in here:

Seems like a niche use case, and I am not sure how to fix it properly (touching files seems inappropriate?), but lets log the issue anyways!
