Emacs Optionally Saving Desktop on Exit With Confirmation

I recently read an article about connecting different Emacs functions; unfortunately I can’t recall the title or url of the article.

After having the idea of that article in the back of my mind for a bit, it connected with one of the things I wanted to do with my Emacs: give myself the option¹ to save the state of Emacs upon exiting.

I knew about Saving Emacs Sessions. The only remaining thing was connecting desktop-save to killing Emacs.
