Stewart,
we've recently had much discussion of this in tsvwg. (And
Fletcher isn't that good...)
My working theory with hindsight is that, in many ways,
IPv6 embodies the worst of all possible choices.

If that is a significant risk, then why did IPv6 not move
to a better protection when it was changing the other things
in the nw/xport interface? After all there were much
better c/s - such as Fletcher - that were well known
at the time?

There's still a risk
of port pollution (IPv4) or destination pollution (IPv6)
from
misdeliveries without checksums.
not
understood != not handled and pushed up the stack.

Yes, I was wondering about this.
If the content is not understood by anyone except the intended endpoint
the occasional misdelivery is surely of no consequence.
