You don't need it for WSL, wWine can already run on Windows natively: http://www.kegel.com/wine/wow.html
Windows might become a Linux distribution someday, the way it's going...
Very unlikely. Linux distributions are based upon Linux, and the whole architecture of the Windows Linux Subsystem, after all, is not having Linux there.

It's not bundled, but it works.
It would be funny if someday Microsoft decides to include Wine with WSL, but I wouldn't be surprised to be honest.
