[Q/A][Java SDK (优雅下线相关)] 请问为啥Dubbo3使用triple协议，没有类似dubbo协议时的优雅下线通知机制，那优雅下线还会生效吗

Apache Dubbo Component

Java SDK (apache/dubbo)

Details

Dubbo协议具体的优雅下线类是这个：org.apache.dubbo.rpc.protocol.dubbo.DubboGracefulShutdown，实现的接口是org.apache.dubbo.rpc.GracefulShutdown。它在offline之前，会主动发送只读事件给channel；
使用Triple协议时，我找不到相关的类，希望社区有同学知道这是为啥；
