Useless or not, the point is: without (ding) this would make the command
do absolutely nothing, which is contrary to the principle that Emacs
should try to provide some feedback in response to each command.

If you use the audible bell, the beeping might indeed be a pain in the
ear (tho I can't really judge: I find the audible bell itself to be
unbearable so I've used the visual bell for as long as I can remember).

So the question is: which kind of feedback should we use instead?
I'd rather keep some kind of feedback.  Maybe a `message'?
