Unfortunately, it doesn't seem to work with your recipe

--8<---------------cut here---------------start------------->8---
emacs -Q --eval "(setq default-frame-alist '((minibuffer . nil)))

evaluate via M-:

(with-selected-window (get-buffer-window "*scratch*" t)
  (with-selected-window (split-window nil -5)
    (set-window-buffer nil (get-buffer-create "*text*"))
    (read-passwd "PWD:")))
--8<---------------cut here---------------end--------------->8---

I also believe that modifying mode-line-front-space is rather a
hack. Nobody seems to do this in Emacs' lisp/ directory. And the
documentation of this variable doesn't encourage its random
modification.

I propose to apply the patch with modifying global-mode-string to
emacs-30. A more sophisticated solution could be in the master branch
then. Yes, the password icon could be invisible due to short window
width, but this might be acceptable.

WDYT?
