   1. The role of many repeated attributes in the URL is to improve performance, and to get the ultimate performance experience by exchanging space for time
   2. `InstanceAddressURL` is a highly reusable object, which greatly reduces memory usage by sharing one object with multiple targets. See https://dubbo.apache.org/zh/docs3-v2/java-sdk/concepts-and-architecture/service-discovery/
   3. URLs are currently divided into `ServiceConfigURL` for configuration and `DubboServiceAddressURL` and `InstanceAddressURL` for recording server information according to usage scenarios. There will be a `consumerURL` attribute for configuring read priority configuration for recording server information. The difference between `DubboServiceAddressURL` and `InstanceAddressURL` is mainly at the interface level and application level.
   4. Based on the above situation, I think our more feasible way is to completely empty the URL into a strict interface, and let `ServiceConfigURL`, `DubboServiceAddressURL`, and `InstanceAddressURL` implement all functions correspondingly.
