[rbridge] Question about the future work 1: Trill over IP

My question about this future work is why not go step further to encapsulate Ethernet over IP directly, rather than encapsulate Ethernet over Trill and then encapsulate Trill over IP?
Consider a future scenario where all edge Rbridges (i.e., ingress and egress Rbridges) are connected across an IP network and Trill over IP is used, do we need to write a new draft describing how to compress/eliminate the Trill header at that time?
My feeling of the current TRILL WG work is copying more fields, options and even OAM tools from IP to Trill. So if there is no abvious disadvantage for using the IP header to replace the Trill header, why not give up the trill header extensions/optimizations and consider to use the existing IP encapsulation and other mechanisms directly ?
