Excellent news.

Presumably if you run the changeset that covers the time over which the
planet dump was made, it will be able to apply all the changes that the
dump missed, and ignore all the ones it got. That way, you will have a
consistent planet replica going forward.

Looking at osmosis, we may not need to do a full planet dump every day
any more - we could just use osmosis to apply the daily changeset to the
previous days planet dump. This could be done away from the main server,
so not place any load on the api.
