I am not an inherit fan of PDF documents at all (hah! You should see my earliest writings about PDF and if you were there for my first PhD student presentation at my first WAIS away day you know how it went when I presented and mentioned in one slide how horrible PDF is) but it has to be recognised that PDF is the de facto standard for academic publishing. It also has the benefit of being frozen, something that has real value for certain uses (archival and more trust in the authenticity of the document).
Doug Engelbart said WYSIWYG should be WYSIAYG: What You See Is All You Get: https://www.invisiblerevolution.net/engelbart/glossary/wysiwyg.html and I agree.
I am trying, with Visual-Meta, to make PDF a Trojan horse with a rich payload.
