Which does not mean that it does not support basic coloring though.  It
does, but hides that fact from any program.

--8<---------------cut here---------------start------------->8---
$ for i in {1..8} {30..37}; do
    printf '\e[%dmA\e[0m ' $i
done
echo
--8<---------------cut here---------------end--------------->8---

‘--color=always’ with GNU (Core|Find|...)utils and other utilities that
support it should also work.

Thus providing its own termcap file for comint-mode (and eshell-mode
also) instead of using ‘dumb’ indeed would be reasonable.
