Now - and this could have some connection to dropping Visual Studio build tools in favor of "all clang, all the time" (at least on Bills boxes) - there aren't even Windows-specific prereqs/build instructions.

I assume it was all just too much trouble for our dwindling pool of hard-working devs, and they preferred to build on Linux systems, and it is easier to cross-compile for Windows from that env?
In my case, I only care about doing 64-bit Windows builds - building and targeting - so I have to ask: has anything been ripped out, such that this would be precluded now?
So, if I install [Windows builds of] clang, rust, python, and whatever else is needed, is it likely that I could complete a Windows 64-bit build of SM?
Related "extra-credit" [possibly dumb-sounding] questions:
0) more of an observation - I used to be able to find bash executables that were actually Windows executables - now all I see is "bash on Windows" means WSL...
1) has Python somehow replaced "make" as the core of the build system?
2) would I be better advised to just suck it up and do Linux-based builds under WSL 2 on Windows, given that I am not likely to create a native (bootable) Linux build env?
