vim doesn't use curses (it's a termcap application).
(n)curses happens to provide a termcap interface.

vim does something like curses optimization, but uses fewer features.

Someone (long ago) commented that vim has some code to explicitly write on
the margin to fool xterm into seeing it as wrapping.

An extension could be added to ncurses to make it do something like that.
Doing it by default would confuse other applications...
