I'd go with experimenting. After all, a diffuse feeling by
Emanuel and me is less worth than hard-nosed experience :-)

So hook away, and either use yes-or-no-p (or its less verbose
sister y-or-n-p), as Emanuel suggested -- or the more complex
(but better tunable) minibuffer stuff. Find out what breaks
(if at all: hunches are, after all, just... hunches :)

Just to get you jumpsterted: this seems to work, more or less.
Fine tuning is left as an exercise for the reader :)

  (defun my-confirm-extra-toppings ()
    (when (y-or-n-p "With extra toppings? ")
      ;; just to show something:
      (set-background-color "lightblue")))
  
  (add-hook 'find-file-hook 'my-confirm-extra-toppings)

Enjoy :-)

Cheers
