I am sorry, but what can be simpler than

     (org-link-set-parameters "man" :follow #'org-man-open)

?

At least, when we only consider Elisp interface.

org-link-parameters

We can improve custom type definition there, but otherwise we do provide
customize interface.

[ Some of the suggestions have been discussed in the past - we do not
  oppose including more built-in link types. Patches are welcome. ]

So, the suggested links are:
1. pdf + page
2. video/audio + timestamp
3. epub/djvu/mibi + page

Note that all these are basically file: links. While we can make users
say pdf:... or video:..., or would be more convenient to extend file:
link instead. Max pointed to experimental proof-of-concept code for pdf
+ page in another email.

I am not sure here. How can we utilize FOLDER? It depend on the kind of
external application or Emacs package we use to open the link.

There is ol-bookmarks package distributed as a part of org-contrib.
Someone with copyright assignment may take a look and re-implement it.

Are there any? I only know web handlers. I did search at some point.
