10.6.3 Installs Rosetta by default?

Greetings! I am using 1.6b2 of InstaDMG/InstaUp2Date. I recently noticed if I add the 10.6.3 Combo Update to my build train, Rosetta gets installed, i.e. the "translate" file at /usr/libexec/oah. I am trying to build a Rosetta free system. I realize it only takes up a small amount of space and is only used when needed, but we don't really need it in our environment. Soon as I remove the 10.6.3 update, "translate" is gone again. Has anyone else seen this or am I just being crazy? Thanks! Steve
