Caution

Caution: one person wrote most of the recent commits.

Why

One person wrote 78% of human commits in the last year, so the project depends on them continuing. (source 1, source 2)

What would change this

A second person takes a substantial share of commits.
Partly checked: maintenance (Commit counts are estimated: the commit sample stops before the window start, so GitHub's totals were scaled by the sampled bot share.)
