If I remember rightly it was even messier than that. You see the note at the top of that file about how the Version 2.0 template requires preservation of message numbers? Well, I think in the original version most of the messages were assigned IDs based on where they ended up in some internal hashtable used by the code, or something equally fragile and dependent on the exact contents of the message template file - so even unused messages would change around the message IDs.
