This was the fundamental question at the center of a long debate in the early days of the "Davids" thread.
Are you renting specific points and the renter can only use them until they expire? Or is the renter paying for the accommodations reserved using those points and still owed compensation even if the points expire because they didn't get the accommodations?
Before the closures, it was generally understood to be the former. The non-refundable status of contracts ensured that owners still got paid, even if the renter cancelled. So points expiring wasn't an issue because the owner was paid for them either way.
Then all
DVC resorts closed for months. Renters couldn't go even though THEY didn't cancel, and things got murkier in terms of whether the renter was still due a reservation regardless of the status of the owner's points.
