I propose that it be added to Emacs, that the
behavior it offers be included, and even made
the default behavior.  It doesn't conflict with
the current behavior - it supplements it.

Which context menus are provided out of the box
can be discussed.  `mouse3.el' gives users and
libraries easy ways to get the menus they want,
but what menus Emacs should provide by default
is an open question.

Emacs is very much a toolkit, and much more.
Emacs Lisp is its core (and some say its
raison d'etre).

Emacs is NOT just an out-of-the-box experience.
It does provide an out-of-the-box experience.
No one _need_ customize it.  But many (most?)
people do.  Openness to customization is a core
feature of Emacs.

You've missed the boat, if you don't think Emacs
is _at least_ a toolkit.

No.  `mouse3.el' (this thread is about context
menus and `mouse-3') offers all of that with a
right-click.

`mouse-drag-copy-region'

(IMO, the default value should be t, not nil.)

`mouse3.el' offers exactly that.
