There were several motivations listed for childless IKE SAs. - remote access, where you create an IKE SA when the user wants to connect, and only create child SAs in response to traffic - authentication only over a physically secure network (not necessarily EAP, but I think this is the use case you referred to) - Location awareness (as in the SecureBeacon draft) - Some "weird" uses such as liveness checks without IPsec, NAT detection, etc.
