1. I agree with your characterization of a
context menu.
2. The `C-mouse-3' is contextual, in the sense
that it shows the major-mode menu(s), and some
items in some of those menus may apply to the
thing clicked on.
For example, Dired mode's `Immediate' menu
has items that apply to the file/dir of the
clicked line. (`C-mouse-3' shows you all of
the Dired mode menus.)
But it's true that most major-mode menu items
don't apply specifically to the thing clicked.
They're generally context-specific (major mode),
but they aren't specific to what you click on.
[We do also have a mouse-3 (and C-mouse-3)
context menu for the scroll bar, BTW.]

3. I agree that Emacs should provide helpful
right-click context menus, and that picking
what's helpful/relevant isn't a simple matter.
And Emacs should provide a way for users and
libraries to easily define their own such, or
improve the default right-click context menus.
I've done this with library `mouse3.el'.
It provides a menu with context-specific items
by default. And it's easy to change what
items are offered. And you don't even need to
give up the ordinary `mouse-3' behavior that
lets you select text and optionally cut/delete
the selection.
