Customizing an Org package alist, Org inserts code that is invalid in
a Beamer context.

Org-latex-classes gives me access to [NO-DEFAULT-PACKAGES].  Not
removing a single element from it as far as I understand.  Or am i
mistaken?

IMO, a wrapper around the header like org-latex-guess-babel-language
would be better, but I don't have strong opinions on this.
