The FAQ link is broken on the page, any ELI5 on what this brings beyond using Arch's package manager and the general goodness of choice? Both of which are awesome in and of themselves, just wasn't sure if there's more here before I jump in.

From what I can gather from the BOW discussion (see my link below), it's a kind of custom arch distro (https://cdn.turbo.run/alwsl/alwsl.sfs). AFAIK WSL is just a rootfs extracted by the lxrun cmdlet. So I guess this replaces Microsoft's rootfs with arch. It seems to be modified to work around some issues in WSL.
