I hate to fan the fire, but what would happened in cassandra if they
_never_ updated their data structures. Or hadoop, or any other open
source project like that. I understand where you are coming from, but
i would like to find an example of a project thats _never_ updated
their datastore or caused some sort of migration, be it configuration
or data based. I _do_ feel we should roll this migration in the least
painful way possible though.
