Hmm, I=E2=80=99m not entirely sure what to think here. On one hand, I very = much agree with you that it=E2=80=99s better if Org is compatible with older versions = just by having a bit of extra code left in org-compat.el. However, if many bits of = Org use Emacs 24/25/26 functions that /aren=E2=80=99t/ covered in org-compat.el= (as I think is currently the case) that leads to bits of Org that are covered by org-compa= t.el and bits that aren=E2=80=99t, and so I imagine this currently produces inco= nsistently buggy behaviour in old versions of Emacs. If this were just a question of fully supporting older Emacs versions at no extra cost, I=E2=80=99d be inclined to respond as you have, but I think the= problem we really have is whether it=E2=80=99s better to provide /partial/ support for= older versions of Emacs? Personally I=E2=80=99m more inclined towards an all-or-nothing ap= proach. All the best, Timothy --=-=-=--
