I have seen it somewhere that way and assumed that Org does support
it. From 14000+ PDF references to specific pages I did not once use
Org link to open such. That was in the queue when I export references
to Org.

If it does not support it is easy to make it by user options.

What I would like to make possible is direct hyperlink annotated PDF
file that does not store any annotations online. And I am thinking
maybe that annotatorjs.org provides that possibility.

It could be something in the following sense:

http://www.example.com/annotator.js&file=https://www.example.com/my-file.pdf&page=12&annotation=my%20annotation%20here

That is how I imagine that. Then we could construct annotating
hyperlinks automatically that do not disturb the user and when opened
the annotatorjs.org could show the annotated PDF file.

If somebody could at least explain if such URL could possibly work
with the Javascript, then I can start from there.
