Fedora guidance is against this fwiw: https://docs.fedoraproject.org/en-US/packaging-guidelines/#_shebang_lines

From a distro packaging perspective using a hardcoded path makes sense, as you want to bind the package to a version of bash you know exists and fully control. From a development utility script perspective that is not packaged and released (such as this one), dynamically resolving bash based on the user's environment makes more sense.
