first thought- MS didn't support SSH?
SSHing into a Windows box with file shares open to other hosts is ... interesting. You're outside the normal user authentication scope, and CIFS/SMB fileshare is (pardon extremely imprecise descriptions) authenticated and contextualized via the desktop login. CALS accounting too, and I've run into exceptionally annoying concurrency limits as a result.
Contrast with, say, NFS or iSCSI where filesystem mounts are managed at the system level, possibly with automounter support for apparently seamless behavior.
My read of this is that this is largely geared at 1) providing additional support for OpenSSH development (a Good Thing), and 2) (finally) delivering an SSH client on the default install.
Really, about fucking time, that.
Though recently some not official versions had malware installed if I'm remembering. I'm wondering if this is a response to that.
Don't worry though, the page has checksums you can validate your download against! Except those are also served over HTTP.
There's also Cygwin, which comes with the OpenSSH server in addition to the client. For a preconfigured Cygwin when I needed it, found Babun to be useful: https://babun.github.io/
