Avoid

Avoid: no human commits in a year, and most questions go unanswered.

Why

No human commits since March 2024, and only 0 of 14 recent issues got a maintainer reply. (source 1, source 2, source 3, source 4)
One person wrote 86% of human commits in the last year, and no human has committed in the last 90 days. (source 1, source 2)

What would change this

A release or merged commit from a maintainer, or replies to recent issues.
A human commit in the last 90 days, or a second person taking a large share of commits.
