I am not sure about this.
The meaning of the prefix argument must be explained in the docstring.
That and the manual are the source of documentation, not the prompt.

Having a short prompt is also good because there are more space
in the line for the command; a short prompt is also better while tipying
a long command: sometimes you want to change something at the beginning:
< ; `beginning-of-buffer'
Now you need to `C-f' several times to jump out of the prompt.  The more
verbose prompt, the more `C-f' you need.

Just my opinion.  Let's see what other people think.
Thanks.
