The pro:s of running 6PE is that one doesn't have to enable IPv6 in the 
core, just at the PE level. It's MPLS label switched by the core, which 
can then be IPv4 only. Yes, it makes for iffy traceroutes but that can be 
"solved" by core hiding.

I don't see anything inherently worse in label-switching IPv6, a lot of 
people do this for IPv4 already (with and without core hiding).
