That is a fair point, though not really fitting my workflow. (Also, my Emacs needs ~20 seconds to start, and I tend to have Emacs uptime of several days or sometimes even weeks.)

This is strange. In my Emacs, C-x 5 0 on the last frame results in "Attempt to delete the sole visible or iconified frame". (And I have `(setq confirm-kill-emacs #'yes-or-no-p)` in my init.el anyway.)

Yes, C-x 5 0 is safe, but I often use my window manager's keybinding for closing a window instead. Customizing confirm-kill-emacs sounds like a great idea, I'll consider it, thanks!
