I was looking into customizing generating code during codegen time - an example would be installing a custom ClientInterceptor for all generated clients at build time. My use-case is that I wouldn't want users of generated library to have to manually add Interceptors that do some generic things applicable to all generated clients.

I see that there's JavaCodegenIntegration interface that is meant to be used as an entry point for extensions during codegen time but I don't see any method that would allow to add an interceptor during codegen. Have I missed something?

For example, smithy-typescript has TypeScriptIntegration interface that contains a method called getClientPlugins:

default List<RuntimeClientPlugin> getClientPlugins() {
        return Collections.emptyList();
    }

Would it be possible to add something similar?
