Hi Pedro.

that be an issue for you?
I don't see that being a problem.

I can try, but I'm not sure I will be able to test it as I don't have a
testing emacs installation. So if it requires many changes, then I won't be
able to do it.

Could you share a bare minimum init.el file I could use to reproduce?
Isn't the code in my initial email (see below) what you need? You need to
amend the load-path entry to the location of auctex.
(use-package reftex-auc)
(use-package tex
:load-path "site-lisp/auctex-14.0.9"
:custom
(TeX-parse-self t))
