Beastiary Feats and Alternative Class Options

[Lord Twitchiopolis]

Some of the class substitution options, such as the Natural Weapon fighting style for Rangers and the Eagle Shaman have the ability to gain Beastiary feats (such as Improved Natural Weapon and Flyby attack) as bonus feats. According to the printing of the Society rules I have, Beastiary feats are prohibited. Is there an exception for these classes that gain axcess to them, or a substitution for the lack of these feats?

I appologize if this is better suited for a "rules" forum, but I figured I'd post it here as it specifically deals with Society.

I believe only if the feat is explicitly called out as a feature (i.e. Multiattack for an Eidolon at level 9) are you able to keep/take that feat.

If offered as an option though (i.e. Improved Nat Armor for Animal Companions), you cannot take it.

I'm specifically wondering about those offered as bonus feats. They are offered as options, but options in a very limited list.
