The current default behavior for org-refile and org-reverse-note-order does not treat Archive headings specially. Consider a .org file:
* Some projects ** Some item... ** Archive :ARCHIVE:... Refiling an entry to "Some projects" results in: * Some projects ** Some item... ** Archive :ARCHIVE:... ** New entry... Would it be desirable to instead append before the Archive heading? * Some projects ** Some item... ** New entry... ** Archive :ARCHIVE:... This could be configurable using a magic value for org-reverse-note-order.
