fredsted's point is that it is not that. It's largely one person's personal preferences. I agree there's some good stuff in there, but there's also a lot I wouldn't like. I don't think it's a superset, just a set.
But how else would you describe a superset? I hate the glass dock and have hated it since 10.5 when it was introduced. You might like it and you'll stick with the default behaviour. For me it's a useful tweak. For you, you can live without it. It's not a superset of preferences - it's a superset of tweaks. Some of them you won't like, some of them are quite nice and this is a good place to find them all.
Or did you mean that you know of a whole bunch of other tweaks that should be on the list? If so, add them and send a pull-request.
There are many legal options one can change with the defaults command. Not all of them are present. Hence, it is not a superset of all configurations. Rather, it represents one person's preferences.
Thank you for sharing. Sorry you triggered an avalanche of whining from the "ugh. This free stuff isn't exactly how I'd do it if I weren't so lazy and I actually did something" brigade.
