Yes, I found the mode line is configurable with the
below Elisp [last]. If you want context (and some more
defuns to do various things to the mode line), check
out the entire config file [1].

For a particular mode, you'll need something like this,
in combination with the rest.

;;;; shell / SHELL
(defun set-shell-mode-line ()
  "Mode line: Set the mode line for `shell' use."
  (set-variable '*mode-line-caption*                     "zsh"   t)
  (set-variable '*show-mode-line-caption*                t       t)
  (set-variable '*show-mode-line-modified*               nil     t)
  (set-variable '*show-default-directory*                nil     t)
  (set-variable '*show-mode-line-buffer-identification*  nil     t)
  (set-variable '*show-mode-line-modes*                  nil     t)
  (set-variable 'column-number-mode                      nil     t)
  (set-variable 'line-number-mode                        nil     t) )
(add-hook 'shell-mode-hook 'set-shell-mode-line)

If you can figure out how all that works, you are a
bright guy. What is dynamic and what is not, is all
intermixed at different layers. But if you do the work
of setting it up (mode by mode, if you want it) I can
guarantee it works, as I used it several years by
now. However, that doesn't say, there isn't a better
way to do it.
