If the class implements the wrong version or isn’t chosen due to its priority then the class isn’t loaded. To do what you are describing would require that serviceLoader load each class and that methods be called on each class to get that information. While that makes life simpler for the serviceLoader it makes it more complicated for the services being loaded.
It should be possible to create a service type that allows you to select 
the appropriate service provider implementation. The service type can 
also work as a factory so that once you select the service provider then 
you invoke some method on it to get the actual logging provider.
