IPv6 does nothing of the sort.

Mandating that a given IP packet arrives on the interface you think it
should arrive on might be a good idea in theory, but asymmetric routing=
 is
a fact of life and checking the routing table twice is additional work =
for
the router.

But that's independent of which particular version of IP you're using.
