Therion would need to use PDF/A-2 because we need tranparency (I think).

And whilst this is mostly sensible why on earth do they think banning
LZW compression is a good idea? That's probably why your file expanded
from 4 to 52MB. The last patents on it expired in 2004 and free
implementations have been available for decades. If it wasn't for that
we could have made it a standard output format (because self-contained
files are a very good thing, and I'd expect my therion PDFs to already
have this property). We can gzip the files after creation but a
foo.PDF.gz is a lot less handy than a foo.PDF with internal
compression.
