[Feature request] I suggest delete-frame command can prompt user for confirmation

[Feature request] I suggest delete-frame command can prompt user for confirmation

I found I always accidentally confused [C-x 5 0] and [C-x 5 o] keybindings. I hope Emacs can add add
prompt confirmation to avoid user accidentally delete frame. Because it can't undo with winner
package etc.

#+begin_src emacs-lisp
(defun my/delete-frame-confirm (origin-func &optional args)
  "Ask user to confirm whether really delete frame.
To avoid accidentally [C-x 5 0] delete frame which confused with keybinding [C-x 5 o]."
  (if (yes-or-no-p "Are you sure to delete current frame? ")
      (apply origin-func args)
    (message "I don't want to delete frame accidently!")))

(advice-add 'delete-frame :around #'my/delete-frame-confirm)
#+end_src

What do you think?

I think it would be annoying and soon you would as often accidentally
say "yes" as you accidentally close frames now.  At least I can say that
it would not work for me.

Wouldn't it be much more useful to be able to restore a killed frame?

Like this maybe?

#+begin_src emacs-lisp
(require 'frameset)
(require 'cl-lib)

(defvar my-killed-frame-ring-size 10)
(defvar my-killed-frames (make-ring my-killed-frame-ring-size))

(advice-add 'delete-frame :before #'my-remember-deleted-frame)

(defun my-remember-deleted-frame (&optional frame _force)
  (ring-insert my-killed-frames
               (frameset-save (list (or frame (selected-frame))))))

(defun my-restore-killed-frame (&optional n)
  (interactive "p")
  (let ((frames-before (frame-list)))
    (frameset-restore (ring-ref my-killed-frames (- (or n 1) 1)))
    (let ((restored (cl-set-difference (frame-list) frames-before)))
      (when (and restored (not (cdr restored)))
        (select-frame-set-input-focus (car restored))))))

(global-set-key [?\C-x ?5 ?t] #'my-restore-killed-frame)
#+end_src

Depending on what's really needed, you can also
just make a frame invisible (and later make it
visible).  You do this by changing the value of
frame parameter `visibility'.

Perhaps Emacs should have this command built-in?  Sounds generally
useful to me.

This is great. Have a way to restore killed frame will be a good replacement for my suggestion.
Thanks for your sharing. Michael.

I agree, this might deserve a vote for this command.

Yeah - we really don't have a solution for this problem built in, right?

Ok, I submitted feature request Bug#51883 raising that question.

Michael.
