tl;dr: The Nixpkgs core team has disbanded after 10 months, citing burnout and an unsustainable workload that conflicted with active technical contribution. The two remaining members blame systemic dysfunction in the Steering Committee—including micromanagement, poor communication, and failure to properly delegate—along with a combative community culture that discourages good-faith governance. Recruitment efforts largely failed, and both members are stepping back from Nixpkgs involvement entirely, with an SC member pushing back on the "micromanagement" characterization in the comments.
