I haven’t dropped the thread, but I’d like to up-level a little:
- I think we might have different models for how documents typically get
produced, and this difference in models results in different perspectives
on what constitutes “easy” and “hard”.
We should compare typical document

I want to back up a bit from the question people normally ask:
“I have a PDF. How do I get the data out?”
to an earlier stage
“I have a PDF I got somehow, and I also have some data I think the PDF shows.
What can I do to make sure the data is easy to get out of (a new version of)
