SPG nights count toward new status (which is years and lifetime nights), and that's easy to tell online, but the legacy Marriott lifetime info disappeared a day or two after Aug 18 (i twas temporarily visible after the changeover). Without that coming back, it's hard to know (through experiments) what counts and what doesn't.
