Lucy, I think the key question is "what is this draft contributing".
IP tunnel specs exist. Creating a network out of IP tunnels is no more a mystery than creating an IP network out of links. Using IP networking to interconnect sites is also not new or difficult. I don't think we need a "standard way" to create a network out of IP tunnels any more than we need a standard way of creating IP networks from links. The whole point of the Internet is the ability to "mix and match" links (tunnels being just links). The only missing piece seems to be network management - i.e., a way to configure these tunnels as part of a network. But that ultimately is just a YANG model for tunnels (i.e., the equivalent of an SNMP MIB). But that's not all that difficult nor does it require a new WG. The rest, AFAICT, is in the hands of network management application designers. We built such an application (the X-Bone Overlay Manager), using our own version of a YANG model/language to configure the components - which, FWIW, are more complex than just tunnels (you need to configure virtual routers too; tunnels are just interfaces on virtual hosts/routers).
