I can't speak to the 200+ IATA carriers, but Delta allows free award redeposits to its top two tiers of elites, up to 72 hours before scheduled travel. American allows free changes of travel dates if origin and destination remain the same, right up to time of travel.
Amtrak's new fifteen-day window seems lengthy to me, even punitive, but I'm not looking at data of typical advance sleeper bookings, and of sleeper award bookings in particular.
