I actually have a clear need for some editable export format (doc, docx, odt, rtf). We are going to use a wiki for teachers to colaboratively edit a huge set of exercises. Some students will access these exercises in the wiki. Others need a printed version. Therefore we plan to export the wiki content and format it as an exercise book.

I have the same issue. The reason is that I want to backup the data indepently from wiki. I still want to be able to edit the files after the export.

Any reason for word document vs a PDF? A PDF export can be implemented relatively easily. A word export, not so much... It would require parsing the document tag by tag using a module like https://www.npmjs.com/package/docx

So unless there's a very clear need for a Word format export, I'll close this request as this is really not trivial to implement vs just using PDF.
