SpringBoot Health probes response changes when additional-path specified

SpringBoot v3.3.3

I added actuator and have the following configuration:

management:
  endpoint:
    health:
      probes:
        enabled: true
      show-details: always
      show-components: always
      group:
        live:
          additional-path: server:/healthz

It provides the following endpoints:

/actuator/health - returns the full health status
/healthz - same as above
/actuator/health/liveness - returns just liveness information
/actuator/health/readiness - returns just readiness information

This is ok. Now, I want to add additional paths for liveness and readiness probes:

management:
  endpoint:
    health:
      group:
        live:
          additional-path: server:/healthz
        liveness:
          additional-path: server:/livez
        readiness:
          additional-path: server:/readyz

This configurations adds two endpoints: /livez and /readyz.

However, these new endpoints are now returning the full health status, just as the health endpoint.

Expected behaviour is of new additional paths is to return just the probes status.

I think this is a duplicate of #40268

Please note that the setting in the https://github.com/spring-projects/spring-boot/issues/40268 just filters the output and still changes it.

Before, with the first setting, the response of probes is:

{
  "status": "UP"
}

After the probes configuration set as specified in the linked ticket, the response is:

{
  "status": "UP",
  "components": {
    "livenessState": {
      "status": "UP"
    }
  }
}

This is NOT the same. If I configure a probe, I would not expect the output to change like this.

Using: management.endpoint.health.probes.add-additional-paths=true works as expected. Thanx
