Thanks! Yeah injecting html in the intermediary document doesn't sound very promising either (again, because the pages have to be built first before footnotes updated with page #s) so maybe I'll abandon weasyprint in this case, if this would be easy to do with a *Tex pdf engine. In that case... how would one go about this? Would a lua filter be more capable with a different pdf engine or would a different mechanism be used?

The problem is that Pandoc does not produce the PDF document: it produces the intermediary HTML document that is processed by weasyprint to produce the PDF. So you cannot get page numbers in a Lua filter.
However, you can inject raw HTML code in the intermediary file (or in your CSS) that will make weasyprint print the page numbers. The question is whether such HTML code exists. It certainly would be possible to do this if you converted to PDF via LaTeX, ConTeXt or groff, but I don't know if it is possible via weasyprint.
