Archetype prerequisites problem

[mjmeans]

Okay, The guide to organized play says for a Cavalier "Instead of the Expert Trainer class feature, Pathfinder Society cavaliers receive Skill Focus (Handle Animal) as a bonus feat."

So the class feature is GONE.

Therefore none of the archetypes that need to replace that class feature (Beastrider, hunter, strategist) are possible, whether or not they are otherwise legal.

AND the additional resources guide for UC says that "cavalier of 4th level or higher may take the Horse Master trait, ignoring the expert trainer class feature. A cavalier who trades this class feature for another as part of an archetype can not take the Horse Master feat."

However, that class feature was already automatically replaced by the guide to organized play, so it's not available to be replaced even if the cavalier takes no archetype at all.

Am I missing something?

I would assume that, in Pathfinder Society, all archetypes have to be read as if the Skill Focus bonus feat was the Expert Trainer class feature, meaning that all alternate class abilities that replace Expert Trainer in regular Pathfinder will replace Skill Focus (Handle Animal) in Pathfinder Society.
