I still have a hope that somebody can point us how to leverage hyperref 
facilities. Adding \hypertarget is a step forward, but ideally internal 
links generated by \ref, links in table of contents, PDF bookmarks 
(table of contents side bar) should consistently use #custom_id anchors 
as well. Usual #section.5 should be a fallback for cases with no user 
supplied labels.

I agree that some complications exist. Just like with HTML files for Org 
ones with <file:another.org::*heading> links. Several iterations of tex 
files compilation are required. .aux files for all .tex files must be 
available to get cross-file links working.
