Well, CMD can also come from user input, so we would need some way for
the user to specify a list of arguments. Currently that can work by
entering a string that would be split by split-string-and-unquote. It
might be more intuitive to actually use a shell and then the user
would enter a shell command (though inserting a shell into things
might bring more complications).
