This prefix binding is sitting on some pretty valuable real estate --- not as valuable as C-o, granted, but still. Is the modifier prefix feature justifying its squatting on this binding? I don't think I've ever used it on purpose, and keyboards with missing essential modifiers are a rarity. Seems like a niche feature to enable with a mode or something.

That said, does the sudo feature (which is great and sorely needed) need such a prominent keybinding? Might M-x sudo be sufficient? People type s u d o in the terminal all the time.
