Adding a group email subscription feature

Would love to see this happen to this plugin as I can see how it would be very useful. Instead of the group admin sending out email that are specific, what if there are users that would like all and any kind of updates that occurs within the group? This plugin (https://wordpress.org/plugins/buddypress-group-email-subscription/) kinda demonstrates what I'm talking about. Can WPMU implement some of the awesome features that would make this already awesome plugin, stellar?
