It really is just legacy and momentum. Recent additions build on sh/bash really well but in the end shell scripting is a means to an end that need to evolve much slower than standard programming languages.
I think bash/sh’s key feature is that they are anti-entropy, there’s no development or evolution so there’s no chance you need to mess with dependencies or new features, the stuff that worked 20 years ago will continue to be the “bread and butter”. By design, this results in a system that’s averse to change and incentivizes people to reach outside of its limits when they are met.
