Ok, I misunderstood.

yes and no, getting a config that will boot on your system can sometimes be 'interesting' (mapping hardware -> config option for example), but should be able to be automated.
the other items that you mention (netfilter, etc) are actually the easier ones to deal with (you know what you want), and also the place where it's impossible to detect what's wanted.

I've seen people talk about creating such tools, but the responses that I've seen have tended to discourage them.
