Thanks for all your work on this, Ryan! So everyone knows, this is hopefully the last major overhaul of MozillaBuild.
The plan from build system land is to attempt to go "all in" on Windows Subsystem for Linux (WSL). That's the feature in Windows 10 (and even in Server additions now) that implements Linux syscalls inside the Windows kernel and allows you to run Linux binaries "natively" on Windows. The performance is pretty good and it is a better Linux-on-Windows approach than msys ever will be. Assuming we can pull it off, the goal is to ditch MozillaBuild and support building Firefox from WSL. You'll then be able to develop on Windows from the comfort of a Linux command line with access to the full power of your favorite Linux distro. We will likely maintain some support for building in non-WSL environments for automation, etc. But for the average developer, we want to focus on WSL because we perceive that to be the best opportunity for a more pleasant development experience on Windows.
