Top: every package Homebrew has ever taken on. Bottom: the same data as a rate, averaged over a rolling year — that is the panel to read for acceleration, since a rising line means the intake rate itself is growing. A cumulative curve cannot answer that: acceleration there is curvature, and whether this curve looks convex depends entirely on where you start measuring. Homebrew reviews every submission by hand, so the ceiling is partly what maintainers can absorb, not only how much software exists.
