There is no provision to negotiate this facility in IKEv1, as you
have noticed. Since the extensions for TFC are in ESPv2, and since we
anticipate folks who use ESPv2 will also use IKEv2, we have not made
plans to create a DOI for IKEv1 that defines a suitable extension.
However, note that one probably could use the ESP TFC conventions
safely even without negotiation, in many cases.
