This is actually a good point I glossed over and is completely correct. You can access the host via its IP but you can fall into application level "not localhost" security checks (Chrome for example). You also have to know that the guest has a different IP to the host and while I can lean on my experience with virtualisation to understand and maybe find a way around the issue, it's an example of the incongruence of WSL2. What you see is definitely not what you get. It's not a fair bar to set for most engineers, especially those who have recently entered the industry or are trying Linux (bash via WSL) for the first time.
