> Even something that should be as simple as piping output from one process to another in Python is a nightmare, and fraught with opportunities to shoot yourself in the foot with buffering deadlocks and other nonsense.
This is true, but when I am writing a script in Python I generally don't need to pipe as often as I do in bash. Python offer many replacements for things that in Bash you need to call another process.
That is, of course, if performance isn't necessary. When it is bash is still unbeatable because of the pipes.

True, you're never going to pipe something to grep in Python when you can just capture the output and use the inbuilt regex capability.
That said, it can be surprising how much worse performance-wise Python can be than shelling out to external utilities. Consider the simple case of downloading and extracting a tarball. I found that check_call("curl path/to/thing.tar | tar -x", shell=True) was significantly faster than anything I could figure out how to do with requests streaming, httpx (async), and the inbuilt tarfile module.
