He may have been talented, just not in network engineering.

While your IPv6 encapsulated VPN would have QOS, the underlying
transport medium (IPv4) still would not (if it didn't have it before).
Furthermore, if any Ipv4 hops in between would have prioritized your
traffic higher based on its type, they now have no idea what is is,
because it's encapsulated.
