ehhh not entirely a useful feature. Neat sure, but meh. Windows essentially killed off the command line in Windows 7 and with each progression since 7 and their transition to app-centric enviroments, I can't think of any use for this beyond simply typing For you. I use the command line every--all--day on both Windows and Unix.
"ssh ip:port - options" instead of "putty.exe -ssh -options"
o File Managment.
Heck, I'm even typing this reply in a command line Vim session.
Git, VIM and scripting comprises a very
small user-base for windows, so small in fact I would wager that the % this will benefit will be less than .1% (based on MS numbers of 110m Win10 installs that's 110,000 people). I say that even with the IDC estimating there are 11m "programmers" in the world.
Two of those four programs listed are personal preference, not a necessity. GIT/SVN have numerous gui alternatives built upon the base cli utility and VIM has plenty of competition with GUI specific editors (talking base VIM, not heavily modified) like VS, Notepad++, and the likes.
Scripting ill give to you as there isn't any real way to run .bats other than in the cli.
I don't see how the resources spent on bringing this to fruition will ever pay off for MS.
