Perhaps you should include engineers from the real world in your deliberations. The IETF has consistently and adamantly refused to accept that NATs exist for security reasons (NOT JUST TO SAVE ADDRESSES!!) and are not going to go away with IPv6. In that regard, please stop inventing protocols that require a masters degree thesis to pass through NATs. (Thesis here: http://www.minisip.org/publications/Thesis_LaTorreYurkov_feb2006.pdf)
Perhaps, many within the IETF understand that NATs exist to generate more address space and they also provide some firewall-like security features. Perhaps some of them might even think that when the additional address space needs are unnecessary, the use of NATs as a firewall is also unnecessary. You might even just use, I don't know, something that is explicitly a firewall and not bother NATing.
If you really want security, having a device which functions explicitly for security might be better than, "Hey, I'm doing this NAT thing because I want more address space at home instead of that stinking single static (most people dynamic, sigh) IP my ISP is giving me. But now that I have 18 quintillion IP addresses at home I can't possibly get rid of NAT and use a firewall that blocks incoming connections because,
