Why is it now easier to manage?
I'm not the OP, but I expect VPNs are easier to manage because you don't have to worry about slicing up the very, very limited IPv4 non-public space and puzzling out how to resolve addressing collisions between all of the various networks you have to manage. With IPv6 you can just calculate a /48 ULA prefix and allocate /64s for your VPNs (and every other internal network) out of that. If ever you run out of room, just calculate another /48 and carry on... easy!
No translation, no subnet allocation issue (because no scarcity), global reachability from everybody to everybody (as internet was meant to be), no overlap (because no RFC1918)
The world is much easier when everybody has its own identity.
