One of the things we grappled with when designing this document was if we should present it as:
a) A self-contained rules document, that wouldn’t require consulting back to the Pathfinder Core Rulebook. b) A list of errata/changes that could be skimmed quickly.
We ended up doing a bit of a mix of both these approaches. We listed all the (core) Pathfinder feats so people could build their characters without having to flip back and forth between books. We also added appendices that quickly list the changes, so folks who are already familiar with the rules could take in everything at a glance.
Additionally, we found that even changing a couple of feats created ripple effects throughout the entire feat tree. We had to tweak the prerequisites and wording of a bunch of otherwise unaltered feats to resolve minor rules conflicts, and including the full feat listing helped us keep track of things.
Hope this answers your question!
