I found opting into this program to be confusing, turning on the subsystem is classic windows obscurity, traversing multiple nested uis to check one single box. When you turn on the insider program it literally does nothing until you reboot it a couple of times. It gave zero indication that it was actually going to update my system and then bam, it starts reinstalling your os.

The subsystem itself has serious problems like being able to get a list of network interfaces which makes running a node server impossible.

I can see why it hasn't made mainstream yet, to me it seems no where close to ready. Running a VM is still the way to go it seems on windows.
