Many rm implementations today prevent you from deleting a path including the root directory, unless you explicitly specify `--no-preserve-root`. Similarly, a lot of compilers tend to warn you or outright stop if they detect code that is very likely to be buggy - the rust compiler warning about these control characters is just the latest example. Of course, in theory, each tool should do its job and the user should be the boundary to know whats right. In practice, though, these heuristics tend to catch bugs-to-be 95% of the time (at least in my experience) and are easily disabled otherwise, so they are good to have.
