This is where I disagree, and think that even a single version number
would be sufficient. I don't think we can say "Oh, this change is
drastic and we can't support your database anymore. Use the other
engine". I think the way is "We support very ancient databases. It's
time to drop the older ones. Use the other engine if you need.".
