Portability is dead now anyways. Something can have "sh" but all you can depend on are sh semantics and built ins. The whole point of a shell script is to compose a larger workflow out of the command line tools preinstalled on a system. I can't guarantee a sh script written on macOS is going to work on FreeBSD or Linux anyways, so there's zero reason to limit myself to sh.
