That’s the theory. In practice, it doesn’t seem to have worked very well. 
The POSIX “personality” for example, was essentially unusable.

When the Windows engineers were working on WSL1, emulating Linux kernel 
APIs on Windows, you would think they would have used this “personality” 
system. But they did not. I suspect it had already bitrotted into 
nonfunctionality by that point.

In the end, they had to give up, and bring in an honest-to-goodness Linux 
kernel, in WSL2.
