So i guess there is a bug in vscode https://github.com/microsoft/vscode-notebook-renderers/issues/189 and it won't render application/vnd.dataresource+json mimetypes, so if this is added, vcsode jupyter will no longer work by default. So this is effectively blocked until vscode can handle this mimetype.
