So we discussed the above page and:
1) how A.6 and B.4 could put simple box push in difficulties (so we need
2) Augie agreed that storing the parent of obsolete changeset at prune
time should be enough to handle case were we miss some changeset (section D)
We'll probably start experimenting with storing such parent information
in the "extra" field of marker. We'll change the format later when are
more confident that no more change are needed.
One of the idea for the format change is to record prune and `changeset
obsolete by its parent(s)` with and extra flag marking it as prune. This
would allow simple backward compat with the existing format.
3) We discussed the Z case a bit. I'll update the wiki soon.
4) the current box push extension should land in the mutable-history
