I'd imagine that it's people at Amtrak who were clamoring for a new tier. The Fred Frailey blog points to this when he discusses how high-spending patrons used Amtrak less after they made Select +.People have been clamoring for a new tier for quite some time now.
What people would that be?
I've seen dozens of posts in numerous threads asking for a more useful region map.
I've seen exactly zero posts in zero threads clamoring for a new AGR status tier.
Introducing Select ++, or whatever it's called, is intended to increase Amtrak's revenue. Restoring the AGR zone map with city names will do the reverse, if it encourages more people to do like me and book AGR awards from zone boundaries.
It makes perfect sense that they do the first and not the second. AGR isn't a charity, it's a marketing tool.
All this assumes that AGR is run rationally, of course.
