Bash specifically as Bash isn't a great target runtime for cross-platform/distro scripts. If a program is simple enough (or the programmer determined enough) to write it in Bash, POSIX shell is a better option, as it's well defined, and well documented what does what, and how. Relying on Bash specifically makes things much more complicated for not much benefit.
