To enact this policy again would mean a tremendous reduction in fare sales and price reductions, as the airline would be liable for refunds on every previously sold ticket. And you can be sure, in today's world, there would be web sites that tracked your tickets and alerted you to a fare drop/refund due.
Among the Low Cost Carriers that US markets against, the US policy is the least consumer-oriented. B6 gives credit for the difference in vouchers, especially if you call during their one day sales (US matches new ticket prices on these sales in competitive markets), and WN lets you re-ticket without penalty on their website at the lower price, with price differences available for future purchase for same flyer.
There are always Spirit and RyanAir to cite as worst...
