I ran the project through PAreview: http://pareview.net/r/129.

Please add a README explaining the module according to the guidelines at https://www.drupal.org/docs/develop/documenting-your-project/module-documentation-guidelines#readme. The README template might help as well: https://www.drupal.org/node/2181737.

From a code perspective I would say we're good.

Thanks for the quick response Eduardo.

Thank you for your contribution! I am going to update the project to opt it into security coverage.

These are some recommended readings to help with excellent maintainership:

• Dries' post on Responsible maintainers
• Best practices for creating and maintaining projects
• Maintaining a drupal.org project with Git
• Commit messages - providing history and credit
• Release naming conventions.
• Helping maintainers in the issue queues

You can find more contributors chatting on the IRC #drupal-contribute channel. So, come hang out and stay involved.
Thank you, also, for your patience with the review process.
Anyone is welcome to participate in the review process. Please consider reviewing other projects that are pending review. I encourage you to learn more about that process and join the group of reviewers.

I thank all the dedicated reviewers as well.

The title isn't supposed to say every Drupal version with which the project is compatible. It's just an indication for the reviewers to understand which code are going to review, or the reviewed code. In this case, it's more important that the code is compatible with Drupal 9.
