That and the manual are the source of documentation, not the prompt.But it's nice if Emacs gives you a different prompt, so that you can be sure you typed in the command correctly.
Confirmation for having typed C-u? Well, sometimes some keys in old keyboards die... ;-)
Just like M-& gives a different prompt from M-!, even though you could figure out the different meaning just by reading the docstring of each command.
These are different commands so its Emacs (and whatever editor) convention to how a different prompt. The OP suggests to use a different prompt for the same command w/ or w/o prefix. There are lots of commands in Emacs accepting a raw, numeric prefix etc. If we change M-! prompt, we might also want to tune the prompt for all of them. Do we want that?
