The problem is worse with transition mechanisms, especially the ones

properly designed application, maybe sufficient. 

I guess I don't understand what "such mechanisms" refer to above.
I don't know if mechanisms like Teredo can provide a stable IPv6
address
when the nat mappings change, but doing TB/UDP for nat traversal
should be
able to provide stable IP addresses/prefixes in this case. 

In practice the NAT mappings do not change and the Teredo address
remains reasonably stable.

unless the global IPv4 address of the NAT box is changed every 24 hours by the ISP...
