WSL is still in very early beta. It works amazingly well when you consider how early this project is. Windows NT has done a good job supporting multiple APIs/subsystems in the past. Windows NT for example does a perfectly good job with the Win32 subsystem - software targeting Win32 for '95, '98, etc. still works on Windows 10, perfectly, despite being a totally different kernel.
