It is an issue if I need to rewrite my scripts specifically for macOS and they are no longer cross-platform.

Yeah, you can alias all utilities called g<something> to <something>, but you can't reasonably expect all users of your scripts to do so as well.

Using macOS is PITA.

If you're using GNU extensions, then you are not writing cross-platform scripts in the first place.
