Even though Joomla 5.2 has some new settings to eliminate duplicate pages, there are still #44263 duplicate pages in the CMS.
I suggest reducing the number of duplicate pages in @joomla.

Describe the solution you'd like

New options for the System - SEF plugin:

1. Redirect pages with ID (articles, categories) to the version of pages without ID
2. Redirect from the version of a page with www to the version of a page without www
3. Canonical links for pagination pages (for pages like ?start=10)

What Joomla has already done to reduce duplicate pages:

• Search Engine Friendly URLs
• Use URL Rewriting
• Force HTTPS
• Strict handling of index.php
• Trailing slash for URLs
• Strict Routing
• WWW redirect
• IDs redirect
• Canonical links

Additional context

This will help eliminate almost all duplicate pages for search engines.
The fewer duplicate pages processed by search robots like @google, @google-gemini, @microsoft, @openai, etc, the less energy will be released by data processing centers, the less effect will be on the environment and climate change.
