    Description

      The ServiceEntryPointImpl encapsulates most of the session management logic and manages the ServiceExecutors. This has an unfortunate side effect that the ServiceStateMachine is initialized by and calls into the final ServiceEntryPoint type:

      TransportLayerASIO::_acceptConnection -> ServiceEntryPointT::startSession -> ServiceStateMachine::start -> ServiceEntryPointT::handleRequest
      

      If we remove the functionality from the ServiceEntryPoint type inheritance and attach it as a member or decoration elsewhere, we can simplify the ServiceEntryPoint interface and make ingress less dependent on the derived type of the ServiceEntryPoint:

      TransportLayerASIO::_acceptConnection -> IngressSessionManager::startSession -> ServiceStateMachine::start -> ServiceEntryPointT::handleRequest
