You are missing the rationale of the PEP process. The point is not documentation. The point of the PEP process is to channel and collect discussion, so that the BDFL can make a decision. The BDFL is not bound at all to the PEP process.
To document things, we use (or should use) documentation.
You are oversimplifying significantly. The purpose of the PEP process is to lay out and document the reasoning that went into forming the decision. The BDFL is allowed to be capricious, but he's sensible enough to choose not to: in cases where it matters, he tries to document the reasoning behind his decisions. In fact, he does better than that... he gets the PEP author to document it for him!
The PEP (whether accepted, rejected, or in-progress) serves as the official documentation of how the decision was made (or of what option it is that is still undecided). If a trivial decision is already made, there's no need for a PEP, but if a difficult decision has been made, then documenting it in a PEP saves years of having to justify it to newbies.
