Some people want to migrate away from IPv4 in their networks. This has to 
be done incrementally, and since encap can be done over IPv4 and IPv6 
without the customer seeing any difference, then this is a good way to do 
things incrementally.

So over time we'll see people migrate from LDPv4 to LDPv6, from GTP over 
IPv4 to GTP over IPv6, from 6PE to 4PE etc.

In the end, IPv4 will be a corner case service tunneled/translated over an 
IPv6 network for most people. We might be up to 20 years out from this 
being done universally, but that's the end goal for most people who have 
actually put serious thought into their long time future. I know people 
who are already trying to do this because they're growing quickly and they 
don't have IPv4 addresses to spare, to waste on infrastructure use, and 
using RFC1918 addresses has lots of operational downsides.
