So how does this work for a reasonable systems administrator??
Who is maintaining a bunch (100?) of W10 PCs?
Ideally he would like to have only one update path to a local store so he doesn't tie up bandwidth for all 100 downloads to "the latest". Keeping updates "internal" to an organization makes the proofing of said updates (do they work? do they break things?) easier to do and publish the results for internal use.
All of this "E.T. Phone Home" stuff looks nice for individuals, but when you need to scale it up, things can get a little bit clogged up.
Oh, well wait and see, and let the BOFHs of the world get a new boss along the way.
