Under the current analysis, honorific (H) agreement is epiphenomenal, and honorification is person feature agreement in disguise. We gain independent evidence for placing first and second person features (1/2P) on an argument introducing head such as Voice or Appl based on the previous literature addressing the Person Case Constraint (PCC). This brings us to the following question: Why are argument introducers recruited for the realization of H? Note that a similar kind of inquiry can be leveled at the following question: Why should the PCC hold? While there are unanswered aspects to these questions, I believe the PCC and the restrictions on honorification can be treated on par with each other. Hopefully, this brings us closer to a unified approach that provides a fuller explanation as to why these restrictions/constraints hold in syntax.
