Does any airline FF program impose a no redeposit, no exchange rule on premium award tickets within X days of departure?

The sleeper award cancellation policy goes too far in my book. It's trivial to implement a redeposit with penalty, whether in cash or points. I can't understand why AGR chose the nuclear option instead.

The first posts of 2013 could well be complaints from folks who lost 50k points despite canceling prior to departure. I sincerely hope AGR is reconsidering this policy. (I'm honestly reconsidering my loyalty to the AGR program.)
