Hi Bjoern,

A few comments:

1) The draft keeps mentioning the end node "policy" but never defines it.
What does "disable IPv4 on this link" mean?

2) Unless you have a crystal ball that predicts the future, the timeline is not useful.
IPv4 will stop being supported when support costs outweigh user benefits, not on an arbitrary anniversary.

3) Do we really need two flags (IPv4 Unavailable vs IPv4 GoAway) for this purpose?

4) What problem is this trying to solve?

All in all, pretty good April Fool Draft, thank you.

David
