I've noticed a few new users are turned off by their first experience with a bbPress install because the think it's so devoid of features and don't understand it's potential. They don't want to be bothered to hunt for plugins to add features, some of which are no longer maintained and don't work (or worse they break the install).
How about in addition to the standard download version, a "plus" version could be offered with a few bundled plugins, hand selected for stability and common feature requests? They could auto-activate after a proper install finishes. A clear notice could be made that Automattic is not responsible for the plugins and how to deactivate them.
