Basically I'm looking to have an HTML template

<html>
    <body>
        <script type="module">
            import CMS, { init } from '@sveltia/cms';
            init();
        </script>
    </body>
</html>

defined as entry point. And I'd like to get a single HTML file as output (and have all dependencies inlined).

With this plugin I almost achieved this with:

having to define a JS entry point, and place the script part in there
defining a tricky custom rollup.config.js which defines the HTML template and allows to inline the script
still rollup copies to the output dir the throw-away entry point script

I've also tried using https://open-wc.org/docs/building/rollup/

It allows to define an HTML entry point as I wanted. But I could not figure out how to inline the script.

It would be great to have best of both worlds in the official plugin...
