I vote for the points are missing forever (not months or years).
If they realign you, there is a gap in usage (3, 6, or 9 months). Yet someone, either the buyer or the seller, is paying maintenance fees for that time period. And now you have a contract whose use year has been realigned (pushed out). Sell it again, what happens? New user gets the new use year (I suppose that supports the missing for years argument, but now they are missing forever).
If it were 'fair' to realign without giving an owner prorated points for that time period, why did Wyndham do that for some (most but not all) owners during the great realignment exercise 10 years ago?
