Arthur T Knackerbracket has found the following story:
Microsoft has announced that Windows Subsystem for Linux (WSL) is coming to Windows Server.
Microsoft's adding it to Windows Server for the same reasons it added it to Windows: it wants developers to have whatever tools they prefer at their disposal.
Sysadmins are also on Redmond's mind, it says. "If you're a server engineer that needs to run node.js, Ruby, Python, Perl, Bash scripts or other tools that expect Linux behaviors, environment or filesystem-layout, the ability to install and run Linux with WSL expands the tools at your disposal on Windows Server."
Redmond snuck WSL into Windows Server Insider Build 16237 without including it in the announcement. It's now issued instructions on how to install it.

What you say is not an impossible scenario, however Cygwin will be needed for quite a long time still as WSL only supports Windows Server 2016 (and probably future versions). Everybody running older systems still need to use Cygwin.
