I wonder if that's used by things like the default epub reader on Kobo? It's sure not used anywhere in the document (at least after what I did to it ).
This sort of id can be useful when comparing a badly OCR'd EPUB with a PDF when you are correcting the EPUB to correct spelling to match the words used on the PDF. It can make it easier to locate the offending word in the PDF if yo know what page it is on.

I doubt if that is why the ids were generated in the first place but I've been very thankful for them on a couple of occasions.
