I think the idea of using PDF/A is that you only have to maintain a single file that contains all the content, without external dependencies like pictures or fonts. It also supports ways to sign the file, to protect its integrity. At least it's how I understand it. Edit: following the link on the parent's profile, there's a few explanations (in https://www.lab6.com/0 https://www.lab6.com/0): """ PDF makes a stand against the churn. I’m publishing this document in PDF because: - PDFs are self-contained and offlineable - PDFs are files. - PDFs are decentralised. - PDFs are discoverable. - PDFs are independent of browsers - PDFs and a PDF tool ecosystem exist today - PDF is an open standard - PDFs are part of the web - PDFs are page-oriented """ (abridged for readability, each of the bullet points are expanded in the document)
