I don't see that there's any difference in responding "Again" to an expired card vs reclassing that card as new. When I'm catching back up on an old deck I just turn new card off and limit my reviews until I've worked through the backlog this way.

Suppose you have 50 unseen cards, and you have it set to show you 5 new cards every day, and energy for about 10 reviews.

Then on day 1 it will want to show you cards 1-5; day two it will show you 1-5 again and also 6-10; day three it will show you 6-10 again and also 7-15 (to simplify somewhat). So you're having some cards you know and some that are new.

If you have 50 cards you've forgotten, then on day 1 it will show you 1-10; on day 2 it will show you 11-20; day 3 it will show you 21-30, and so on -- all completely new. That makes it far more of a grind.
