There's a version history at
http://en.wikipedia.org/wiki/Portable_Document_Format#Versions
that shows the main changes between successive PDF versions.
I don't actually see much related to compression since 1.4,
other than adding JPEG2000 image compression which would certainly
not help any for our docs.
So at this point I'm wondering if the reported size difference is
really PDF-version-related or just indicates inefficiency in the output
from pdfjadetex. If the latter, it might be fixable without creating
compatibility problems. It's not something that interests me enough
to put work into, though.
