I get afraid that folks take this list too seriously. This list is simply a place to air "crazy ideas". Hopefully, a crazy idea that has potential gets traction, but i have not seen that yet.  I see the same old stale ideas that have failed in other venues get recycled and respun here.  More tunnels and more NAT to solve a problem we don't have....

But they are tools we have in our collective toolbox. Some tools don it work well for certain tasks.

I think the evolution within 3GPP is that the mobility system (GTP) is getting smaller and smaller, more and more distributed, so relevant innovation flows over the top, e2e gets restored....... If i am using netflix today on Wifi, and walk out the door and switch to LTE ... there is mobility there at the Netflix side....it just works ...  This is a problem solved at the application layer, we do not need complicated network layer things trying to insert themselves.

You are making a good point.

But it comes down to where you solve problems. And if you do it at the thin waist of the architecture then you solve mobility N times in each application.

5G is simply millimeter wave small cell spectrum and marketing.

Well I think some people are trying also to make the 5G infra lower OpEx. Today the ~$50 cost to phone users can cover the infra costs. But what about when IoT devices which will be dirt cheap will need dirt cheap 5G service. Will that cover the high OpEx? Volume won't help the equation because greater scale will need to be dealt with.
