[X] I had searched in the issues and found no similar feature requirement.

Apache Dubbo Component

Java SDK (apache/dubbo)

Descriptions

Allow modules to extend Dubbo application configuration to support custom configuration in other modules. For example, I expect to define MetricsConfig in the dubbo-metrics module and PromethusConfig in the dubbo-metrics-promethus module. And in the future, I expect to define OtlpConfig in dubbo-metrics-export-otlp.

Example : https://github.com/walklown/dubbo-pr/commit/043561fe9fb79c762876f89cd6e428a8a4f12b39

Question :

AbstractConfig can be removed so that the Config class will be more generic . Is this improvement necessary? I hope to get some suggestions
Is SPI a good way to implement extended configuration classes? Any better suggestions?
