Reasoning about and manipulating included PDFs. This is much harder
with a two-pass engine like XeTeX + postprocessor; as an example
compare the knowledge of XeTeX (the program) and pdfTeX about included

I doubt the speed gained from that is high for most documents.

But as I said: Show us your code.
