This count is not comparable across projects: each project's automation decides which of these events a person emits.
About 8% of issues opened in the past year have never received a reply. 61% of open issues come from outside the core team, a mix of external reports and the maintainers' own roadmap. Work labelled "support: commercial" is answered fastest, typically in about 10 hours, while "scope: scheduler" waits about 7 days. 66% of tracked open issues have had no activity in three months, so the open count overstates what is actively being worked. 79% of issues opened in the past year have been closed, leaving a working backlog.
