Maybe its something to do with [this](https://docutils.sourceforge.io/docs/user/rst/quickstart.html#document-title...) since all plugins have "a unique adornment style at the beginning of the document." being `=` underlined. Since the plugin name is therefore in the title, not a `<h1>` in the content, I suspect (but havn't checked) it won't be copied into the resulting page by the script that plugs the `README.html` into the final page with the navigation sidebar etc.
