Is Blog Defaults Plugin still useful in WP 3.1?

Is the New Blog Defaults plugin by Deanna Schneider still useful for Wordpress 3.1.x Multisites? So much changed with the update that rolled multisite functionality into the Wordpress core I am really not sure if we need this plugin any more. Does anyone have any experience with it?

I know it doesn't get updated very often, there have been bugs and the plugin author is often not very responsive. Plus I just want to streamline everything, so this is one I'm looking at.
