> Again, nice in theory, and sometimes that might work, but it has lots of failure modes. For example, you can end up with nonsensical Z's that neither of you would otherwise find particularly worthwhile or compelling, even though you both agree that, yes, Z would improve things slightly.
I think that's where negotiation is a stronger frame though, because that sort of debate generally comes down to "how do I get through this faster", and the negotiative framing is "I disagree, but it doesn't matter, because the thing I actually want is for us to stop having this conversation, how can I achieve this with the greatest efficiency", or phrased otherwise, "what do I need to give you to make you go away?" Which there is much less to talk about.
