If they hear from members that those benefits are too difficult to reach, they'll add another 5 or 10 elite-qualifying nights to the card (maybe with a spend requirement) to bring the head-on-pillow requirement back down to 50. Hyatt did almost exactly this, moving Globalist requalification from 55 to 60 and then within a few months including 5 qualification nights with their revamped CC.

Lifetime Platinums who aren't eligible to become Lifetime Titaniums are exactly the group who should be wary of future changes on the way.
