I think this would make sense if it was a compendium, but this is an arbitrary subset of everything you could possibly set via defaults, with no rhyme nor reason to what is and isn't in the list other than "this particular guy cares about these particular things".

I can imagine being annoyed at any number of things, but that doesn't mean turning them off is a good idea.
Security is all about layers, and disabling an important layer (and especially a layer you'll rarely trip over once you have all your commonly used apps downloaded) doesn't strike me as a bright idea. It only takes one bug in your browser of choice to con it into launching an arbitrary executable, or one asleep at the wheel moment to trick you into double-clicking a cleverly icon'd malicious app; the quarantine is your mitigation against such events.
Completely agree - but someone has to keep this compendium somewhere, and why not keep it as a piece of working code, rather than as a web page or something? If you end up having to use a lot of different Macs and have to set up new accounts for yourself on a regular basis, what you'd probably do is fork the project here, eliminate the stuff you hate, and then that's your acceptable-mac-environment-maker script.
occasional disastrous idea (killing the executable quarantine).
Out of curiosity, why is this disastrous? I'm not a fan of the idea, but I can imagine how someone might come to hate com.apple.finder.quarantine badly enough to do this? Maybe this particular tweak should be commented out by default, though.
