Hi Sam, link stability is a concern I've had too. I currently have a fix
(or at the very least, an improvement) for this in my config where I
overwrite org-export-get-reference. (see:
https://tecosaur.github.io/emacs-config/config.html#nicer-generated-heading).

I raised this on the list a while ago ---
https://orgmode.org/list/E1jxAjq-0004Dk-LH@lists.gnu.org/ but there
didn't seem to be much interest.

All the best,
Timothy
