Hi Marcin,

I think that it makes more sense to display help as the default behaviour rather
than inserting the help at point.  The use case for this behaviour is when the
user wants to know what a command does in a brief way without showing the
help buffer.

Therefore I'm against making this change.

To get your preferred behaviour, you could advice
describe-key-briefly, for example like this:

(defun my-flip-second-arg (orig-fun &rest args)
  (apply orig-fun (list (car args) (not (cadr args)))))
(add-function :around (symbol-function 'describe-key-briefly)

If I don't hear any protests, I will close this bug report as wontfix.

Best regards,
Stefan Kangas
