But it's nice if Emacs gives you a different prompt, so that you can be
sure you typed in the command correctly. 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.

Yes, it's better to keep the prompt short if possible. Still, having
the extra feedback might be worth it.

If the command is a single line, you can use C-a instead to avoid the prompt.

M-e leaves the prompt immediately.
