Part of the problem is that it is really REALLY hard to figure out what the actual objections are. I asked, and the one clear answer I got was one subjective opinion that the cognitive load exceeded the benefit. Great! That's one person's concern. I've responded to that by clarifying parts of the cognitive load problem, and that's about as far as that can go. But if there's nothing more specific than that, what do you want me to respond to? How can I address the objections if the objections are as vague as you're describing? > At a minimum, the PEP should state the objections fairly, and note > that the PEP author disagrees.

Yes, and "significant opposition" doesn't just mean "I don't like this". There's nothing to respond to in that. (Plus, there's significant belligerent support for the proposal, which is even harder to handle.)
