features complex variable

Hello,

How you usually(or not usually) deal with complex variable in features? :)
Let's say my feature holds some content type which should not publish author/date info. To make this happen I have to change theme_settings[toggle_node_info_MY_CONTENT_TYPE] but feature can deal with whole theme_settings only and therefore any new content type will make it not sensible overridden.

So far I am thinking to use install hook instead of strongarm for such changes...

Thanks.
