Yes, this was our conclusion as well after moving our core to PTX1000/10001.
Personally I would recommend turning off LSR payload heuristics, because there is no accurate way for LSR to tell what the label is carrying, and wrong guess while rare will be extremely hard to root cause, because you will never hear it, because the person suffering from it is too many hops away from problem being in your horizon. I strongly believe edge imposing entropy or fat is the right way to give LSR hashing hints.
If you need to load-balance labelled IP traffic though, all your edge devices would have to impose entropy/fat. On the hand a workaround at the edge at least for EoMPLS would be to enable control-word. Lukas
