I'm sad now ;+)

Even if I will own a dual-stack UE, I won't be able to communicate with my IPv4 stack if that communication was initiated through IMS :+(. I'll be forced to use my IPv6 stack and go through a surely less efficient translation mechanism (in comparison with native end-to-end IPv4).

I can not agree with that.

As you said tunneling is an option, so what about DSTM (that solves temporary IPv4 address assignement, and allow the use of end-to-end native IPv4 flows) ?!
