When personal Emacs environment develops than it becomes rather
tedious to do it in Bash when there are many prepared and ready
functions from Emacs Lisp. The more environment is developed and user
knows about it, the easier it becomes to think with Emacs handling
stuff that common users would otherwise handle with the shell.

Sure, like eshell. ;-)

I would use any program if it satisfies the purpose. Within `mutt'
email client I will use `fzf' and `psql' to choose some items from the
database and completion and tabulated list mode to choose items from
within Emacs. So it really does not matter. What user knows or prefers
personal and what is more useful shall be first chosen.

If you don't rely, then don't, otherwise Bash script can be developed
very similar to Emacs lisp with a lot of reusable functions.
