My hope is that agents will be allowed some flexibility for the flyer who booked their domestic ticket on say August 15, 2020, particularly if travel restrictions are in place during her/his travel.

I am glad to see the 3 day rule go away. I understand what they were trying to prevent, but I think that their new way of selling flights (i.e. not giving away firesale miles seats the day before travel) kind of negates the need for that silly rule which just felt mean spirited to me.
