Xcode template madness

so today i wanted to order a little the list of Xcode templates, as user templates normally are placed in random locations: some in the preferences, some in the user library and so on

this is the list were both the standard templates and the user templates are
/Developer/Library/Xcode/Project Templates
/Library/Application Support/Apple/Developer Tools/Project Templates
~/Library/Application Support/Developer/Shared/Xcode/Project Templates/
/Developer/Platforms/iPhoneOS.platform/Developer/Library/Xcode/Project Templates

(the last one is for the iphone templates)
