related to #1439: How do I activate cache Expiration for js commentbox

Thank you for your message.

I would strongly advise not removing jdoc:include type="scripts" from your template. This is a core Joomla mechanism responsible for loading scripts across the system, and removing it will very likely break other extensions or essential Joomla functionality.

Regarding commentbox.min.js: although the file size is noticeable, it is delivered as an ES module, which means it is automatically deferred and therefore does not block rendering of your page. For this reason, applying fetchpriority="low" or relocating the script is not necessary in most cases.

At this time, I recommend keeping the default loading behavior to ensure optimal system stability and compatibility. That said, I can consider introducing an optional lazy-loading mode in a future version — so that the CommentBox script loads only when the visitor scrolls into the comments area. This could further improve perceived loading performance for pages where comments appear lower on the screen.

Please let me know if you have any further questions or suggestions.
