            The PR most likely needs to run full matrix of tests because it modifies parts of the core
            of Airflow. However, committers might decide to merge it quickly and take the risk.
            If they don't merge it quickly - please rebase it to the latest master at your convenience,
            or amend the last commit of the PR, and push it with --force-with-lease.

            The PR is likely OK to be merged with just subset of tests for default Python and Database
            versions without running the full matrix of tests, because it does not modify the core of
            Airflow. If the committers decide that the full tests matrix is needed, they will add the label
            'full tests needed'. Then you should rebase to the latest master or amend the last commit
            of the PR, and push it with --force-with-lease.

            The PR is likely ready to be merged. No tests are needed as no important environment files,
            nor python files were modified by it. However, committers might decide that full test matrix is
            needed and add the 'full tests needed' label. Then you should rebase it to the latest master
            or amend the last commit of the PR, and push it with --force-with-lease.
