Actually almost everyone will *still* need a rendezvous service as even 
if there isn't NAT66 (which I strongly suspect there will be, as nobody 
has magically solved the rest of the renumbering problems) there will 
still be default firewall filters that the average end-user won't know 
how or why to change (and in some cases won't even have access to the CPE).

For the former we can only hope that NAT66 box builders can get guidance 
from IETF rather than having IETF stick its collective head in the 
sand... for the latter the firewall traversal has a chance of being more 
reliable than having to traversal both filtering and address translation.
