We had a survey from users about two years ago:
Doing such surveys where you ask people to participate is nice to get a view on the community, especially when the survey is specific and the results are shared afterwards. Apps have also a section here on the forum, each developer can also ask for feedback.
For survey modules, some people will oppose to an automation to share more or less automatically data, you create such an infrastructure. If there is a bug they might share more than they want, … especially that might be one of the main reasons not to use big cloud providers.
