I love bash for anything that doesn't need to scale. The reason is reliability. I can't tell you how many times I've run into problems with python or similar on small library implementations. If I need to make an http request in my code and I'm using curl in bash and something fails, I can pretty much guarantee the problem is not curl itself. It's battle tested and deterministic. However the python script that forgets to wrap a try catch or configure proper tls auth or some other quirk? I have had those eat hours/days of my time and having to resort to tcpdump to sort out what's really happening. Same with SQL libraries/ORM vs SQL cli, same with Json/xml parsing libraries vs jq etc.
