Offering to maintain telephone_filter

These offers need to first be created on the project issue queue, even when the person asking for more permissions is already co-maintainer. As per Offering to become a project owner, maintainer, or co-maintainer → , they can be moved in the Drupal.org project ownership queue → , 14 days after the offer was posted/moved in the project queue, if the offer has not been declined from other maintainers (including the project owner).
Remember to provide a link for the project page, in that case.

Since the project is covered by the security advisory policy, project moderators will only add as co-maintainers/maintainers people who can opt projects into security advisory coverage.

The project owner is no longer active on drupal.org, so contacting him would not have any effect.

I am moving back the issue to the project queue, since there is nothing project moderators / site moderators can do in this case.

I am closing this issue since there has not been any follow-up action as described in How to become project owner, maintainer, or co-maintainer → from the person who opened this offer.
