What would be the reasoning? I mean not many operator& overloads make sense, including a deleted rvalue one, but I don't see a reason to needlessly introduce a corner case to the language.

Does it make sense to be able to 'delete' something that isn't automatically provided? You can't apply & to an Rvalue anyway.
