Have you seen an actual deployment in the field, forwarding IPv6 traffic
inside MPLS? My use-case would be to remove BGPv6 in the core, the same
way I removed BGPv4 from the core back in 2008.

I know LDPv6 can do this, but support across multiple platforms is not
where it needs to be yet, making network-wide deployment impractical.

Mark.
