They've made it pretty clear that to prioritize they've been following the 80/20 rule as best they can with the data they have. They try to prioritize the things people do most often in each iteration because they don't have the budget to do 100% of the things all at once. (And it probably is a waste of time to upgrade settings features that 0% of people use.) The big real complication is that data they have available on what is used 80/90% of the time is telemetry. It's not a coincidence that the people that find that the settings they use the most that haven't been converted are in the set of people most complaining about telemetry and most actively disabling it.
