It appears that this bug has been fixed for Emacs 27.

Surely the most important thing is telling you what each mode does.

Knowing how to turn them off is important, but once you know how to
turn one minor mode on or off, then you know how to turn *any* minor
mode on or off -- it's the same in all cases.

(I do think there's an argument for showing the mode symbol rather
than a capitalised variant of the name in the `describe-mode' help;
but that's a different conversation.)

But even if you follow the link, it still won't tell you how to
*interactively* enable or disable the mode (e.g. with M-x MODENAME);
so if a person is so new to Emacs that they don't already know how to
do all these things, I'm not sure that your suggestion is sufficient
to resolve that situation.  And once they do have that very basic
understanding of modes, the information is pretty redundant.

I don't think I'd be bothered by the information being added, but I'm
not sure that its absence is really a significant problem?  I suspect
you'll need more people to add their agreement to the bug report to
convince people otherwise.
