Due to PHP Bug #53727, is_subclass_of might return inconsistent results on some PHP versions if \N1215\Tsukuyomi\BootstrapperInterface::class can be an interface. If so, you could instead use ReflectionClass::implementsInterface.

            throw new \InvalidArgumentException('bootstrapper must implement' . BootstrapperInterface::class . '.');
        }

        $this->bootstrappers[] = $bootstrapper;
