It appears that the Poison Darter archetype(Blood of the Beast pg 9) for Ranger has a dead class feature. It keeps the Quarry class feature from Ranger 11, however is unable to actually use it since the target must be one of the Ranger's chosen favored enemies which the archetype trades away all instances of.
There are also no compatible archetypes that I could find that would trade away Quarry but nothing else that Poison Darter does(replaces: Favored Enemy, Master Hunter, Wild Empathy, Hunter's Bond; modifies: Combat Style Feat).
My interest is for PFS, so a simple campaign clarification or additional resources comment would be sufficient for my purposes. However, as there currently isn't a campaign clarification for it, this should be considered a general rules question/errata request.
