Rationale:

• The PR modifies multiple files in different directories. This indicates a large change that could potentially impact other parts of the codebase.
• It adds new dependencies to pip3 install command which might introduce new bugs or unexpected behavior if not handled properly.
• There are changes related to CORS configuration, which is a common practice for handling cross-origin requests in web applications but it's not clear how these changes will be used in the application.

This PR requires careful review and testing by experienced developers as it involves significant changes that could potentially impact other parts of the codebase or introduce new bugs if not handled properly. The CORS configuration changes are also worth noting, which might require further investigation to understand their implications on the overall system architecture.

Please note that this is a general assessment based on the provided information and may need additional context for a more accurate categorization.

Can we use the version of aiohttp-cors shipped in Debian ?
https://packages.debian.org/bullseye/python3-aiohttp-cors

Should we remove the duplication with a custom decorator that wraps custom_cors(...) ?
