I listed 5 elements (certainly not a comprehensive list, just a work in progress) that a good map should have. That's not subjective in the least. If your map does not have those five things, it likely is not a good map.
AFAICT this is circular reasoning. Your list of five elements was arrived at according to your preferences. You could make a case for your preferences, and try to show that a large group of people would find your criteria useful. None of those things are objective though.

The idea that there can be no objective judgment of art is counter to pretty much every form of criticism out there.
Well, there are really degrees of objectivity. Say for instance someone decided that "humor" were supposed to be a key component of a module. Then a module could be judged for humor, which would itself be subjective. But the likelihood that I'd share a common definition with the reviewer regarding "humor" is greater because "humor" is a more precise term than good. But humor is not as objective as temperature.
IMO there are huge groups of people out there that don't understand the difference between subjective and objective. And what I'm really talking about here is the scientific method which even fewer people understand. People who want other people to take their opinions seriously do not like relativism because it runs counter to their desire to communicate preferences to others and be understood.
So if you want to propose a list of criteria for maps, that's fine with me. I wouldn't say you're wasting your time because it's not objective. All criticism and reviews by nature are subjective, but if you're clear enough about what you're doing (by listing criteria, for example) than someone else can come along and at least have a better chance of understanding what you're talking about.

However, it's uselessly overpedantic to write off anything less than absolute objectivity as subjective.
Well, useless for what? As I said before, I think I agree with your approach of listing criteria in a review. I would find your opinions on maps broken down according to the criteria you outline to be useful. What I find troublesome though would be to throw out the elements and just call things "good" and "bad". IMO that kind of clumsiness creates a sort of orthodoxy that is unhelpful in a creative field. I'm not saying you suggested that, so hopefully you take some of this as just statements and not refutations of anything.
If I use the fact that the sky is blue to "prove" that all artistic criticism is useless, you might want to examine the chain of reasoning rather than debate with me the color of the sky. I think the problem is that you believe that I'm equating subjective with useless - which is not what I've tried to do.
