> I always feel uncomfortable since it's hard-code

I used to think this as well, but I've since come around to the opposite view. Having it as a "requirement" for what's likely the most popular cli execution strategy enforces a (somewhat disorganised but still useful) defacto standard across all scripts. I can open up any repo/gist/pastebin in the world & chances are if it's intended to be run, it'll contain this handy little statement of intent on the first line. I might not actually run (env-dependent) but I'm sure I can make it.

On the env-sensitivity though, if e.g. you're running nohtyp, as another commenter mentioned, /usr/bin/env has that covered.
