Of course, I did not mean it for org-mode buffers! ;)

Indeed it does work.

But, unless I am mistaken, this is exactly the definition given here:
http://orgmode.org/manual/Translator-functions.html#Translator-functions
and so I was not wrong, this used to work as I expected.

I suspect that this change (regression?) will cause problems to a lot of
other users when they will upgrade their org to the current version.

Would changing the last lines of `orgtbl-to-latex` to something like this
work as a long-term solution?

    (require 'ox-latex)
    (let* ((*orgtbl-verbatim* (plist-get params :verbatim))
           (backend (if *orgtbl-verbatim* nil 'latex)))
      (orgtbl-to-generic table (org-combine-plists params2 params)
backend))))

Thanks for your time,
