The changes in your webrev look okay to me although I assume we need to 
be cautious about back porting until it becomes clear if Windows Server 
2019 will be re-released or not.  The Windows Server blog [1] suggests 
that the release is paused while an issue is investigated and maybe a 
re-release will mean a new build number at least.
