I agree to all Morten except that creating this feature is "boring". From my personal view its extremely exciting to create a data collection module including its server infrastructure. Due to its complexity and the need to have access to the wordpress.org backend or at least the need to know the WP infrastructure makes it hard for the average wp contributor to work on this and it must be coordinate or done by a dev who is deeper involved.

It can be started as a single plugin but can not be used by others giving them any beneficial feature. So noone will start with it until someone from the core team fires the gun and says: "Do it and we do everything to add it into core soon." So yes, more leadership is needed.

I am pretty sure if the direction is clear someone would like to work on this.

The discussion is starting again. So let's hope that someone will jump in.
