Exciting, but let's see how long this takes to be released (not to insiders). I was excited when WSL 2 was announced, but it took almost a year to be released to stable. I had immediate needs that WSL 1 couldnt meet, and I could not run Insiders builds in my environment.
By the time WSL 2 actually was out, I had migrated completely to Linux. I'll keep checking MS progress here, but in many ways they already lost me and many others.
