We already have that in `echo-keystrokes'.

But I'm thinking also of times when you do C-u M-! and then switch to
another window to copy the command, then maybe when you come back, you
don't remember 100% what you were doing.

M-& and M-! are practically the same command anyway, async-shell-command
is basically just

    (defun async-shell-command (command)
      (shell-command (concat command "&")))

IMO yes, if the difference can be summarized in the prompt concisely
enough.
