The advancement How Did We Get Here if previously completed does not currently reset for needing the Darkness effect unlike the other advancements. I checked this on a copy of my 1000 day hardcore world and this was just opened in the snapshot.

this advancement requires having all effects on at once and normally should be reset any time a new effect is needed making one have to get all the effects again to complete the advancement. I believe others have needed to do this in the past when a new effect came into the game. I'm not entirely sure but it should have taken the advancement away forcing me to get it again but with the darkness effect. Otherwise I'm not sure.
ManosSef is correct, this hasn't happened with other changes before, which weren't a separate criterion.
Intentional. An advancement that doesn't have multiple requirements, like Adventuring Time (which says 0/52 when you don't have it) cannot reset when it is edited.
