problem is two fold:
1: Enlarges the driver, which affects those who use the driver over a
network connection (some people still use JDBC direct in applets)
2: It becomes sensitive to changes during development.
An example of #2 is where the Timestamp format changed just slightly, then
getTimestamp broke.
