Description
There are many unsafe blocks e.g.
https://github.com/search?q=repo%3Auutils%2Fcoreutils+env%3A%3Aset_var&type=code
https://github.com/search?q=repo%3Auutils%2Fcoreutils+env%3A%3Aremove_var&type=code
Can we remove them or use without unsafe{} at least from one-thread utility?

Research direction
Start by reviewing the repository-wide usages of env::set_var and env::remove_var linked in the issue, then identify which usages belong to one-thread utilities. Determine whether those paths can avoid unsafe blocks without changing behavior. Done means the applicable utilities no longer require unsafe environment operations and their existing tests still pass.
