There was this mail from Microsoft, offering support in case Windows 10 would raise console problems with cygwin: https://cygwin.com/ml/cygwin/2015-04/msg00623.html While this was particularly about the console, maybe this offer could be used for a request to provide official documentation of that system call, so it could then be used?
