If anything the dci should start cycling older standard blocks. It rewards people who played in those formats, sells old useless packs of weaker blocks, and would act as a control mechanism for standard card prices. It also freshens up standard!
Just think about mountain of cards that instantly become subpar during the transition between formats. This is the main reason why everyone's flocking to legacy in the first place, because they hate seeing their cards rapidly depreciate after two years especially during these times. People would actually have an incentive to keep older set cards... If they spread the use of other cards around, they wouldn't have to worry so much about hyperinflation that results in a few specific cards when the other cards become subpar.

I'd be pretty happy to see some slower magic games with "old cards," playing some shivan dragon, serra angel, or nightmare where they're competitive again instead of being reprinted, like great boxers fighting beyond their prime.
