I can only speak for me.  When looking at the mode line I want to see
the diff numbers in nearly all cases, and I don't want distractions when
using Ediff, so I made them outstanding (red).

But that's the same mouse tooltip as the rest of the mode-line of the
control buffer has.

Those mouse bindings are not "Quick Help" nor Ediff specific, they are
the very basic bindings from mouse.el:

(global-set-key [mode-line mouse-1] #'mouse-select-window)
(global-set-key [mode-line mouse-2] #'mouse-delete-other-windows)
(global-set-key [mode-line mouse-3] #'mouse-delete-window)

No problem about the tooltip - but that doesn't explain why "Quick Help"
is displayed.

The "quick help" is what you get when you hit `?`.  Look: Without the

  (setq ediff-window-setup-function 'ediff-setup-windows-plain)

setting, the control frame doesn't display a mode-line, but after
hitting `?` it does, and the "Quick Help" info gets visible.  My
interpretation is that 'ediff-setup-windows-plain has been added later,
after quick help, and the "Quick Help" string was never intended to be
visible all the time.  Plausible?

Michael.
