General function in plan Org program files shall not be modified in
the main development branch to serve a specific PDF reader on specific
OS system as that is hard coding and there are many PDF readers which
all behave in different manner.

Instead it is better if you make your custom link for Org that does
what you want.

It looks as being possible to be customized by using
org-link-abbrev-alist

Is it?
