I suppose you meant without customizations, you have to re-teach. You
do not have to do both.

I think internal consistency between mouse-1 and S-mouse-1 also
matters as well as behavior of S-mouse-1 across applications.
Shift should modify operation by mouse-1. I think `extend region' can
be regarded as modified set-point; however mouse-appearance-menu has
significant distance from set-point.
How about A or B?
A (global-set-key [C-S-down-mouse-1] 'mouse-appearance-menu)
A (global-set-key [S-down-mouse-1] 'ignore)
A (global-set-key [S-mouse-1] 'mouse-save-then-kill)
B (define-key cua--cua-keys-keymap [S-down-mouse-1] 'ignore)
B (define-key cua--cua-keys-keymap [S-mouse-1] 'mouse-save-then-kill)
