Unfortunately Steve and I don't see eye-to-eye on everything, and this
is perhaps one of the more prominent issues.

I'll save you several years of arguments, on and off-list, and simply
say that the "safe" option, and the only option I'm likely to ACK,
would be to add new fields at the end of existing records. We have
made exceptions in the past, but those were pretty extreme cases.
