Indeed, these are more like Gnus's `M-i` (as well as a few other such cases, PCL-CVS also had such prefix commands) in that they are somewhat specific to a (set of) commands, whereas the other examples I mentioned tend to be usable with "any" other command (tho they may end up doing nothing in many cases).
