Having the nasty mind and thoughts such as mine, I am inclined to think that the whole insider program was, from the start, some kind of confidence trick to make the public feel they were part of the so-called "development". All the items, so far mentioned in successive insider updates, could easily have been incorporated into the existing, initial Windows 10, as Normal "Tuesday" updates.
My own observation is that, with regard to my initial statement, Windows has come to the end of the line as far as the OS is concerned. It can only be, now, added to with utilities (but which ones?)
I have, over the past couple of years, only been a casual visitor to the Insider site, bu I can read, from the voluminous feedback, That it, alone was largely falling on deaf ears - admittedly, most of it being so repetitious and, in many cases, pointless.
Sorry, my opinion only.
