Isn't the whole point of PDFs that they (mostly) don't change? They represent content as laid out on a page.
So, IMO this is neat if it's new tech for reading PDFs and extracting data from them (and maybe leveraging current under-used features to store more machine-readable information), but bad if it's about introducing even more complexity into the PDF documents.
Perhaps 10 years from now we will have responsive PDFs, but I feel sorry for whatever damned soul is going to have to expand hard-coded limits in order to fit the new PDF specification text into a single PDF document.
