Reselling OKW now with 2057 expiration also helps with the 2042 issue. The less product they get back all at once the smaller that issue will be, as they might only have the "problem" of getting a few years of inventory for free all at the same time.
Realistically they are paying $100 per point for rofr right now, if they have to pay even 5 years of dues before they can sell it they're way ahead (especially since they could also rent them during those 5 years)
Edited to add: if they don't want too much inventory, they could always offer existing owners of those intervals a one-time deal to repurchase (eg $125/point for a full renewal). Many would take that, even if just to resell later, which would drop the inventory they need to carry even further.
