Watch out, because errors would probably be silent and remain lurking in
the shadows.

You would not, because when you run

--8<---------------cut here---------------start------------->8---
exec fish "$@"
--8<---------------cut here---------------end--------------->8---

it replaces the Bash process, so exiting Fish would effectively
terminate the direct child process of the terminal which would then close
automatically.
