Why does Micronaut discard everything after hostname for client url configurations?

Question

When configuring Micronaut Http Clients in the application.yaml I was unaware the url must only be the hostname and port, if anything more than the hostname and port is included then it is discarded by Micronaut when it chooses the host to call. The Micronaut Configuring Http Clients documentation doesn't explicitly warn the reader about this behavior.

Is this behavior expected? If so then what options are there for users who are dealing with long URIs, i.e.: http://localhost:8080/application-name/v1.0/controller-name/endpoint

Demo Code

BadClient.java

@Client("bad-client")
public interface BadClient {
    @Get("/hello")
    Maybe<String> getHello();
}

GoodClient.java

@Client("good-client")
public interface GoodClient {
    @Get("/server2/hello")
    Maybe<String> getHello();
}

application.yaml

micronaut:
  application:
    name: micronaut-client-issues
  http:
    services:
      bad-client:
        urls:
          - http://localhost:8080/server2
      good-client:
        urls:
          - http://localhost:8080
  server:
    port: 8080
    cors:
      enabled: true

When the good-client is used it works as expected, but the bad-client throws a '404 Page Not Found' with the following log details:

The URLs are supposed to be just the URL without a path. If you want to supply a context path, you can do so via config:

micronaut:
  http:
    services:
      bad-client:
        urls:
          - http://localhost:8080
        path: /server2
