I wonder, if WSL2 is no longer directly tied to the core OS, doesn't that limit its usefulness and "raison d'etre" a bit? I thought the whole benefit was that it was tightly integrated and you could run Linux with very little overhead. If you just run Linux in a VM it doesn't sound very much more useful than just spinning up Linux in VMWare or Hyper-V which has been possible for ages.
To be honest I haven't used it that much as I generally prefer to run my Linux bare metal but I just wondered about this bit after reading that.
