Just wondering.
The Knowledge skills were kept for the Knowledge domain but nothing else as far as I can tell:
Knowledge (nature) for the Animal and Plant domain
Survival for the travel domain
etc
Probably because they're not as needed. Having a class skill at max ranks and a cross class at max ranks is only ever a difference of +3, so it's not nearly so hard to make a cleric have appropriate skills at appropriate ranks without dealing with half ranks...
