The Final Comment Period with disposition to accept for [RFC 0146] Meta.Categories, not Filesystem Directory Trees by AndersonTorres · Pull Request #146 · NixOS/rfcs · GitHub has started, and, barring any blocking new issues raised, RFC is to be merged on 2024-07-08.
As the RFC calls for a maintainer team for the category list itself and resolving doubts about the use of categories when raised, volunteers for the team are also welcome!
