It would be good if you could make HTTP post requests to access pages that live behind forms, e.g. a thank you message to contact form request or a "members" area behind a username and password login form.
This is possible within PhantomJS simply by specifying it as a post request and giving it the appropriate variables. If you could specify these in the uncss syntax then these could be passed through to PhantomJS.
