Indeed Emacs could use the same 'C-down-mouse-1' to select non-contiguous
regions.  In fact the Emacs rectangular region is a special case of the
non-contiguous region.  So implementing the non-contiguous region selection
would require just writing a pair of short functions.

Regarding a mouse binding for the rectangular region selection,
maybe 'C-M-down-mouse-1' still would be a good choice after all,
while 'C-down-mouse-1' should be reserved for the more general
non-contiguous region selection.

Another variant is not to bind 'C-M-down-mouse-1', but use just
'mouse-1' after the rectangle selection mode is activated by its
current key sequence 'C-x RET'.
