Recently, ASF GitHub repos had their defaults for GitHub Actions changed to "always require approval for external contributors". In Slack, Karan pointed out that Airflow has recently submitted a ticket to have that changed back: https://issues.apache.org/jira/browse/INFRA-24200. IMO, we should do the same. I don't think we have a problem with fake PRs, but we can always improve our responsiveness to contributors from outside the project! Every little bit helps, including running CI automatically.
If others have opinions on this, let me know. I'd like to raise our own ticket to change our default. Gian
