I can't speak for everyone obviously, but I have plenty of lecturers that insist on .doc/.docx handups and after an incident where a basic document (as in headings, page breaks and paragraphs as the only formatting) written in Libreoffice ended up in a 5 column layout on Word for no explicable reason, I'd rather just write them in an application that I know will show the same when the lecturer opens the file as when I open it.

If your workflow is push-only, exporting to PDF fixes this. I have Office loaded on my iPad only for extreme situations. Also, I have Office 365 through my institution that I've been known to use once in a blue moon. Most of my document creation these days is org-mode -> PDF though.
