After some private email from Scott:
The registry also assigns 7 to TP/IX, which became CATNIP.
So 7 also needs to be changed to Reserved and RFC1707 and RFC1475
both need to become Historic.

If we are doing this, then I think that CATNIP (RFC1707) needs to be made
Historic at the same time, even though it didn't need an IP version number.
I also recall rumours that some people were actually using ST2 at one point.
Are we sure that it's totally gone away?
