Regarding the remaining Org-mode `lacks a prefix' warnings and particularly in light of the recent message on emacs.devel [1] would it not be sufficient to simply alias date and entry locally:
--8<---------------cut here---------------start------------->8--- (defvaralias 'org--date 'date) (defvaralias 'org--entry 'entry) --8<---------------cut here---------------end--------------->8--- Presumably this would be backwardly-compatible, and given a subsequent name change in diary-lib.el a very simple integration test could catch that very quickly. If I get a positive response I can perhaps look at a patch and tests, but if my understanding is amiss I will appreciate the heads-up. Best, Martyn p.s. I should point out that my personal view is that a serious well maintained Emacs library such as Org-mode should have a zero warning policy for official releases.
