So then this is not a real problem, and we shouldn't be worried about
it, right?

I don't see what discoverability has to do with this.  The issue is
not discoverability, the issue is to show reasonably useful context
menus when the user turns on context-menu-mode and right-clicks some
part of the Emacs display.  Telling the user to do more customizations
_after_ turning on context-menu-mode makes little sense to me.
