I am well past the phase of trying to pull everything into emacs. All reasons to not use eshell you mention are valid, and I can add one more: vanilla eshell doesn't really work well with visual commands.

But recently I installed eshell-eat, and my biggest paint point just went away.

I never expected to use eshell as a full-blown terminal replacement. I use half A dozen aliases (find-file dired...) , some lightweight lisp scripting, git that, apt install there... That's about it.

In that capacity it's a valid quick tool.
