What do you mean by "in a general sense"? (because "services" is such an overloaded term i am not sure which aspects of services you are referring to).

We will require iteration order of service instances to work with ServiceLoader in both classpath mode and module mode.

E.g.:

  // list of FQCN of a service provider class to control service instance iteration order
  // for those classes that are present
  List<String> l = ... 
  ServiceLoader.orderWith(l).load(ServiceInterface.class);
