Should synthesized NAT64 addresses be preferred over native IPv4? #42

This is an open question I do not have an answer for yet - I guess the arguments can be made for both approaches..

So if an IPv6-mostly network provides DNS64, then a dual-stack host talking to an IPv4-only destination would have a choice between:

a synthesized IPv6 address which will be routed via NAT64
a native IPv4 path

(we have a similar discussion in https://datatracker.ietf.org/doc/draft-link-v6ops-claton/: shall CLAT be enabled if both PLAT and IPv4 are available?)
