Therefore we will keep the code as is. If we do not add this package in the presence of explicit CJK fonts, we don't produce compilable documents. ctex is (IMHO) orthogonal to this.

And it appears when the default font is lmroman. Setting the main font to 'Noto Serif' got rid of the message. The other option is the LATEX_HEADER in your proposal plus #+LATEX: \ctexset{space=auto} which I got from https://emacs-china.org/t/help-implementing-better-out-of-the-box-xelatex-export-in-org/30405/6 (thanks LuciusChen for this!) With that, using lmroman will not trigger the warning and it will not interfere with fonts that define the 200B character. Which begs the question whether a solution with an extra document class for this could not be the cleanest answer in the future.
