Powershell support for SMA online scripting is targetted for a 2020 release.Jeremiah J. Reed commented
Lack of native Powershell support, on an appliance that mostly maintains Windows boxes, is no good!
We are considering a Windows 10 Universal app but this would be a large effort that would delay all other work on K1 GO for an extended period. As such we are continuing to monitor for demand/adoption before taking this on. Please continue to vote and comment to help drive our decision.
