Comment:
There is no discernible benefit to using `zsh` as `sh` and a lot of potential drawbacks. Substituting `bash` for `sh` is one thing; several popular distributions use `bash` as `sh` and a wide range of shell scripts with a `/bin/sh` shebang are probably widely deployed and well tested with `bash`. (I don't really like this; script writers who specify `/bin/sh` should make sure they aren't inadvertently relying on bashisms; this common practice leads to sloppiness.) I'm almost certain that the vast majority of shell scripts written for `/bin/sh` have *never* been tested when interpreted by `zsh`.

I vote against adding an alternative here.
