You are right - the lack of use cases is contributing to the lack of direction. Maybe what I'm asking for here is "How do you want to use something that generates PDFs from a layout + parameters?" ...
Maybe I do have an idea after all. What would make it the most easy for me (and many others) to use is to allow CSS + HTML to be a feed interface.

I realize this is a daunting suggestion that may not even be a good idea but it would be sheer genius if it could be done. I don't know the first thing about PDF internals but perhaps it might map fairly well...? Or maybe there is already an engine out there that could handle the interchange?

horizontal scrolling (and possible janitor
