I think autoupdate is mainly there for the transition phase. Since submodule can e.g. contain a lot of files a checkout would take much longer. Similar to when Jens implemented the recursive diff, many people were annoyed by the new files showing up and some with the impact on performance (thats why we have the --ignore-submodules option). In case of very big submodules and people already ignore their diff it might even be necessary that the update is only done manually. E.g. for a big media repository.
