You're free to do this, but be aware that you'll then need to be aware of where your scripts will and won't run.

I regularly use Fedora, Alpine Linux, Void, Debian, and OpenBSD. Void uses dash as its default shell, Debian uses it as /bin/sh but still includes bash, OpenBSD uses another POSIXy shell, Fedora uses Bash. macOS also uses zsh as /bin/sh.

If you want portability, you don't have much of a choice. Devs not caring about portability is why less common operating systems are a struggle to use which only fuels monocultures.

Standards compliance and implementation diversity have a symbiotic relationship that is necessary for the health of open platforms. I described the benefits in more detail in a blog post:
