 Why not? Just curious. I would think it would be very beneficial to have
 that. That way, not only could we migrate data between plugins more
 easily, but since WordPress would know what data came from where then it
 would be able to allow us to remove all the plugin's data upon uninstall
 rather than trusting the plugin to do it itself. After using a bunch of
 plugins for years on one site, it can get messy with the dead files being
 left around by old plugins you've deleted.
