The entire Internet routing table doesn't have to be centralized in the
core and it doesn't even have to be done by what are now called routers.
While most will instantly pronounce it as unworkable without even trying,
source routing or routing at another layer is an alternative way at dealing
with this problem.  Excuse me while I quote out of order, you say:

Should IPv6 routing just be IPv4 routing with bigger addresses?
