There are some environments where `opcache.restrict_api`(https://www.php.net/manual/en/opcache.configuration.php#ini.opcache.restrict-api)

```
PHP Warning:  Zend OPcache API is restricted by "restrict_api" configuration
directive in /tmp/vendor/typo3/phar-stream-wrapper/src/Helper.php on line 34
```
