Yes, it does.
I can only add that ncurse's endwin() calls _nc_mvcur_wrap() with 
putp(exit_ca_mode) inside. So we do not need to manually operate with 
*_ca_mode capabilities neither under slang no under ncurses...

Well, let's try to investigate it :)
As far as we can see in changelogs, it is old entry (since 1994).

Sat Dec 17 16:06:51 1994  Miguel de Icaza  <miguel sphinx>
        * terms.c: do_enter_ca_mode now enters putp's the enter_ca_mode to
        the screen.  Moved from main to avoid name space pollution, this
        should make the A/UX port work.

Wed Feb 15 00:46:33 1995  Dugan O. Porter  (dugan b011 eunet es)
        * terms.c (do_exit_ca_mode): New function; the counterpart of
        do_enter_ca_mode().  Called in main.c.
        * main.c (view_other_cmd): Now calls do_exit_ca_mode(), and it
        isn't disabled any more just because OTHER_CURSES is defined.

2001-09-15  Pavel Roskin  <proski gnu org>
        * ... Call do_exit_ca_mode() and do_enter_ca_mode() even with
        ncurses.

Pavel, do you remember - what for?
