对Event事件上下文有个疑问

[joker-hong]

   public static function decode(string $buffer, TcpConnection $connection): Request
    {
        static $requests = [];
        $cacheable = static::$enableCache && !isset($buffer[512]);
        if (true === $cacheable && isset($requests[$buffer])) {
            $request = clone $requests[$buffer];
            $request->connection = $connection;
            $connection->request = $request;
            $request->properties = [];
            return $request;
        }
        $request = new static::$requestClass($buffer);
        $request->connection = $connection;
        $connection->request = $request;
        if (true === $cacheable) {
            $requests[$buffer] = $request;
            if (count($requests) > 512) {
                unset($requests[key($requests)]);
            }
        }
        return $request;
    }

workerman中http的$request已经是单独实例化了$request = new static::$requestClass($buffer);，属于局部变量了，为啥webman中还需要把请求弄个上下文呢？Context::set(Request::class, $request);

这里是局部变量，但是这个对象到了外部，webman框架会存储它，以便业务调用request()函数时返回正确的request对象

明白了，谢谢大哥，还有个问题，webman的插件都是围绕着Event/Select来开发的，但Revolt/Swoole/Swow这三种事件又需要连接池，那这样是不是现有的插件不支持切换到这三种事件呢？
