I want to report that I can use the new version of the SVG (2.00b) LaTeX directly. The developer (Falk; Bcc) said that there will be a new release soon. I attach an example of the strange things that I can achieve. I hope that it's useful :) .

If all you are doing is replacing includesvg with simplesvg, then you
might try this:

#+BEGIN_SRC emacs-lisp
(let ((org-export-filter-link-functions  '((lambda (txt _ _)
                                             (replace-regexp-in-string "includesvg" 
"simplesvg" txt)))))
  (org-latex-export-as-latex))
#+END_SRC

If you are doing more than that (it looks like you are adding options?)

in your init file after you load org, and then it will shadow the
ox-latex function and you might not have to change anything when you
update as long as no incompatible changes are in the update. I know,
that is hacky, but it works in cases like this.

then one alternative option is just put a copy of your modified function

Hello,

I once tried to create a filter (is that the name?) to modify the
function which exports SVG files. Verdict: I suck! Thus, I keep
modifying the ox-latex.el every time that I upgrade (see attached).
Would someone please tell me what is the right way to achieve that
(without modifying the code, please? Thanks!
