Is there something like make-obsolete-variable for this case that would give a warning in init.el on this variable? I am not the only one setting it to nil https://github.com/search?q=3Dsetq+bidi-display-reordering+nil&type=3Dcode https://emacs.stackexchange.com/a/21761/730 :) so a warning might stop some other poor user from wasting half a day on a pointless debugging mission. (The manual also mentions the variable's effect without saying you shouldn't set it https://www.gnu.org/software/emacs/manual/html_node/emacs/Bidirectional-Edi= ting.html )
