Hi, I have seen that `org-latex-polyglossia-language-alist' contains far more languages than `org-latex-babel-language-alist'.
Well, if I'm not mistaken, the situation in the LaTeX ecosystem is this: Polyglossia appeared as a babel replacement for XelaTeX and LuaLaTeX, since babel, at that time, had no support for these two new Unicode based TeX engines. I think those two separate lists in ox-latex.el translate that situation. But the reality is different now: babel has full support now for LuaTeX and XeTeX and supports more languages than polyglossia (and also supports language variants. See http://mirrors.ctan.org/macros/latex/required/babel/base/babel.pdf p. 20). In addition, babel is part of the LaTeX core and is, therefore, better mantained. Of course, anyone who wants to use polyglossia in their documents can keep doing it without problems. But I think it does not make much sense to mantain in ox-latex.el two separate lists today. Maybe, for simplicity, it would be better to unify the two lists in a single db, something like `org-latex-language-alist'. What do you think?
