The main drawback is that I'm used to all the goodness that comes by default and have to get used to how primitive Bash is when I'm forced to use it.

I also prefer fish's scripting syntax (and built-in utilities) over bash, and some people don't like installing fish to run my scripts.

Nushell is far from fish in terms of interactive usage, and I find the scripting language to be too unstable for writing scripts you want to keep in the medium term.
