This is interesting. Although I think it's wise of AS to get ahead of potential issues, I agree with everyone who has pointed out that this offer just isn't tempting. If they want to stick with a measly $35, it might be more tempting to some if it was offered as an actual refund as opposed to a flight credit. Otherwise, they just need to up the ante. The only folks likely to jump on this are the ones who were considering changing to a later flight anyway.
