Exactly. And if one needs more space, then we need to talk about getting
MTU discovery also being able to scale up. See other threads ;)

That is because there are people who do not want to change the work they
have been working on for a long long time.

Though I appreciate the effort that a lot of folks have stuck into it.
Fragmentation (and Flow Labels...) are not matching the ideas used on
the current Internet.

We have learnt a lot of over the close to 20 years that IPv6 has existed
and a lot has changed in the Internet during that time.

As IPv6 is in a way still in it's infancy we have still the possibility
to make changes to it.

Lets not hold "but I did a lot of work on that back then" stop
possibilities of fixing something that will be used for another 50 years.

Unless one wants to start doing this whole "IPng" thing again a lot
sooner than that...
