It also has a bit to do with how much they're actually used. Merlyn wasn't a series regular until season 3 and he was a later reveal in season 1 and was only in about half of the episodes. Savitar was revealed late and missed a few episodes after reveal.

As for the Speedy and Oliver Green Arrow photos, I think they should be included, as should Arsenal. We don't remove Eddie, Adrian, Tommy, Kendra, Cat, etc just because they are no longer series regulars so why should identities be removed? We don't have to go with all versions like including Hood, Arrow, Green Arrow, but maybe just distinct versions like Spartan and Diggle Green Arrow.

Based on case law, I think Hawkman's various reincarnations need to be included in the bottom of the box, as well as the Duet doppelgangers. If the ancestor of Stein is included, then those should be too.
