Its purpose is to consider being more open about the data collected regarding our plugins' usage. Such data is invaluable to developers, it would definitely benefit them if more was available. I am not suggesting to add more widgets to the plugin's page at this stage, I know how hard it can be to display simple yet comprehensive information. Rather I am suggesting to give access to the raw data to the plugin's maintainers, or better, to everyone.
