~3 years ago, and literally anything. I was trying to see if org-mode could serve as a long-term store of info (i.e. decades), so multi-OS and "likely to have other working implementations" or "can re-build by hand if necessary" was critical. Since then I've just settled on a pile of markdown/commonmark files that interlink when desired, and I'm pretty happy with that. Everything essentially just said "use emacs, that's the only implementation and the only spec". So I tried orgzly for a bit (it's handy), but ultimately decided it's a "hard no" for things with only one impl.
