At the end, our official policy is simply supporting the latest version of third-party tools we need to cooperate with. However, yet another policy is to not break Org documents that worked in the past. That's way I prefer to be over-cautions and support more things, especially if such support is not too difficult. The idea with adding multiple legacy escapes seems simple enough to do it once and forget. > If org-mode did that, it could ignore the `CW` font whose history I just > went to the trouble to explore, and the problem with `\,` and `\/` > escape sequences as well.
