I respect the work of the people you mentioned, and most of the configuration I gathered is from both of these sources, but I don't want to limit this to only drupal, or worpdress but also other applications. Unlike YHager's repo I would like to update this with all possible security rules and maybe better organize it. On the other hand Grace's configuration is extremely bloated. I don't really need or afford a system with aegir, varnish etc.
With advices from you I would like to do this very modular, so that when someone needs a certain configuration or rules for just a specific module, it will be available. That's why I posted this here, to get feedback. I still have a long way, but it will be soon a good reference point for a simple nginx machine.
