org.apache.dubbo.registry.client.ServiceDiscoveryRegistry.shouldRegister是不是有bug?

* Dubbo version: 3.0.5
* Operating System version: all
* Java version: 1.8

代码：
String side = providerURL.getSide();
boolean should = PROVIDER_SIDE.equals(side); // Only register the Provider.
但是调用此函数时，URL是发送到registry注册的URL，side字段已经被移除。
这导致了所有provider都不能在ServiceDiscoveryRegistry注册，从而导致如下的日志不停刷
