    Jordi,

    unless I'm reading an earlier version, unlike MAP-E/T, lw4o6 is 
    optional. From 
    https://tools.ietf.org/html/draft-palet-v6ops-rfc7084-bis-00#section-4.4.7:

    " The CE router MAY support lw4o6 functionality"

    regards,

    Yannis

The rationale for this: Many service providers try to avoid the CGN, and lw4o6 is a way to do so, without increasing the cost of the CE. Basically, a CE that supports a regular IPv4 NAT+DS-Lite, is already capable of supporting lw4o6. The cost in terms of CE flash memory for DS-Lite is about 1Kb. The open source package available for DS-Lite that I’ve been digging-in takes 6Kb, but already includes also support for both MAP versions.

Those protocols are the 3 alternatives that a service provider has to deploy IPv6-only WAN, but at the same time provide dual-stack in the LANs, with practically the same functionalities or even more, that what CGN requires. At the service provider network, it requires, instead of CGN, a stateful NAT64 (which cellular providers are already using) or a Border Relay (for MAP). Basically, a CE needs only 3Kbytes of code in the flash to support CLAT (the CE part of 464XLAT). The support for MAP (both versions and also lw6o4), requires about 6Kb.
