I said "redoing it every time it changes".  Wouldn't that keep the serial
number in sync?

But the only field in the SOA record that's relevant to any server other
than a slave is the MinTTL (it's used for negative caching), so it doesn't
really matter whether the serial numbers are kept in sync.  It's less than
a minor wart, it's totally irrelevant.
