 docu-notion is not doing anything smart with regards to previously Published but now not Published documents. All it does is ignore every Notion document that doesn't have `status == Publish`. So if the old version of the document is still in your file tree when your static site generator (e.g. Docusaurus) runs, then it will appear on your website. If it isn't there, it won't. If you rename directories or move the document, docu-notion will not realize this and will delete the previously published markdown file.
