I'm sure most desktop.el users do.
My point was that I'm particularly inadequate to think how to extend the desktop feature, because my use of Emacs in general is atypically simplistic: one frame (two on very specific occasions), no speedbar, no toolbar, few windows. And I don't keep Emacs running for long or use it in daemon mode. I usually start Emacs many, many times a day.
