Cavalary: The number of Prime keys is quite high and seems to be increasing, so it's a matter of how well the moment when they become daggered is chosen, according to the number of keys left, the time till expiry and expected desirability, but if they're moved there when they're about to expire, you'd want them to be requested quickly, by whoever, so they won't go to waste.
I agree that rules should never cause keys to expire when there's people who'd want to claim them, but I don't think there's much risk of that with my proposal. What I've seen BenKii do so far is to move them to daggered something like 2-5 weeks before they're set to expire (depending on interest shown? or probably just his own available time), and then if needed, mark them "no activity required" when there's less than a week left.
Reconstructing it for the last batch: on 1 nov the following keys were moved to daggered: 15 thronebreaker (exp: 11 nov), 2 lego hobbit (expiry: 22 nov), 11 greedfall and ~20 tomb raider: legend (exp: 6 dec). Of that batch, all keys except for tomb: raider legend were gone swiftly, and had people requesting them when they were already gone (so there definitely was more interest than availability), while a few early birds requested multiple of these keys.
