https://google.github.io/styleguide/shell.xml "If you are writing a script that is more than 100 lines long, you should probably be writing it in something else"
I have build scripts of complex systems that are >1000 lines. They are easy to understand and maintain and I cannot image doing it in another language.
Bash is good for switching yard code, where you're gluing a lot of program invocations together with a few variables and a little bit of logic. It can certainly do other things, but that kind of code is the least risky when it becomes big.
If folks are being honest with themselves, they will find it's significantly more sane to rely on a Python interpreter being available than writing Bash scripts. Go binaries have less dependencies than any Bash script, if runtime dependencies are an issue.
There are actually quite a few incompatibilities between different implementations and versions of many of those utilities. Even if you try your best to restrict to the POSIX standard it's quite easy to "accidentally" use an extension, leading to breakage when someone runs it on Linux distro $foo or macOS.
Dependencies is a big problem in shell scripts, much more so than most other environments.
