Cool, I didn't know this. There are already quite a lot of Apache Projects there: https://sonarcloud.io/organizations/apache/projects, and INFRA seems to be very open to adding more projects: https://issues.apache.org/jira/browse/INFRA-19555 Do you know if GH PR integration is also available? (so that it shows a warning in the PR if inspections on the change trigger)
