Software PKG, Update PKG, MPKGs?

Just curious, are people deploying MetaPackages for software + updates? For example Office 2008. I've got individual packages for the base installer, the first update, and then the 12.0.1 update. I've also created a MetaPackage that contains these packages, and will continue to revise it as new updates get released. Is there a good deployment argument for or against this with InstaDMG?
