It should have been submitted as a bug report instead.

Well, it did say

  Toggle dynamic word-completion on or off.

And that "word-completion" part is not really boilerplate.  But yes,
the doc string was clearly insufficient; I've fixed that now on the
emacs-29 release branch.

You can find the full documentation of this mode in the commentary at
the beginning of completion.el.

After turning the mode ON, type at least 3 characters of some symbol
and press M-RET, perhaps several times.  You will see the mode in
action.
