Exactly that is the reason.
DNS64 is still being usable in some situations where the network
operator has no control over the end device.
To make 464XLAT useful in most situations, operating systems need to
provide support for 464XLAT by default on all network interfaces. IIRC
this isn't the case for Windows yet (support for WWAN exists) and most
Linux machines also don't have such a service enabled by default.
As long as that is the case, DNS64 is an intermediate solution,
although not for all stuff, especially when using software without IPv6
support.
