    # We prefer to use an "exclude-list" so that new "default" exclusions are not
    # automatically inherited. We can decide whether or not to follow upstream
    # defaults when updating golang-ci-lint versions.

    # (unlike the "include" option), the "exclude" option does not take exclusion
    # ID's.
