LegacyKernelServiceInitializerImpl.reverseCheckConfig is only used in bootCurrentVersionWithLegacyBootOperations and in that test I don't see any point in using non-management services. But to disable those, the user has to LegacyKernelServicesInitializer.configureReverseControllerCheck(AdditionalInitialization.MANAGEMENT, null). Which is obscure and seems unnecessary.
