This is not very surprising at all. The use of PowerShell is completely analogous to using shell scripts on linux, along with making use of things like the GNU core utils and other nearly universally-installed utilities (curl/wget, tar, etc). Traditionally there wasn't a lot you could do purely from a shell or scripting environment on Windows -- all the "good stuff" was in Win32 APIs, hence needing to ship binaries. Microsoft has been adding everything to PowerShell, to the point that you can now do nearly anything you can do with the GUI -- and in many cases more, since most of the administrative commands accept a -ComputerName parameter and are integrated with domain authentication. It's only natural to take advantage of that.
