Fully agreed. I have no problem being in 6PE until fork-lift in some future to IPv6 core and 4PE.
Assuming your addressing will continue to grow on IPv6, and remain reasonably static on IPv4, your forklift should allow you to remain native on both (on the basis that at that time, we do have native control planes both for MPLSv4 and MPLSv6, of course). So "4|6PE" would not be necessary. Personally, I think it's unnecessary labor to remove IPv4 in the future, especially when it's not expanding. One is welcome to do this, of course, if they are really bored :-). Removing native IPv4 in the future only to replace it with 4PE seems quite complex, to me.
People have too sentimental view on this, if you label your IPv4 it is silly not to run 6PE, you're just creating complexity and removing functionality.
Turning on native IPv6 in your core is not adding complexity, I think. Yes, agree that you may lose parity between MPLS-TEv4 and TEv6 as of today, but some would say that MPLS-TE adds quite a bit complexity today, especially if used on a long-term basis. Mark.
