                !is_subclass_of($class, MetricInterface::class)

Due to PHP Bug #53727, is_subclass_of might return inconsistent results on some PHP versions if \flipbox\craft\scorecard\metrics\MetricInterface::class can be an interface. If so, you could instead use ReflectionClass::implementsInterface.
