Thanks, it wasn't out of doubt that I asked, but it seemed having a reference to point at would help resolve the contention. The Docker blog post covered a lot more detail, even about WSL2, which was really informative and I hadn't seen.
I wonder exactly how much work "container" is doing in that Microsoft blog post's description, because it doesn't seem like it's the same kind of environment as a runc or containerd container?
I also wasn't quite sure how much detail to infer from the behavior of vmmemWSL or vmcompute.exe, because my casual understanding is that there's some adaptation layer that handles mapping Linux calls to Windows calls. It seems reasonable to allow for process mapping or accounting shenanigans for any number of good reasons.

This was how WSL1 functioned. It used a shim layer, and honestly it was pretty neat for a lot of the basic stuff. It fell apart if you were doing more complex/advanced stuff, however, as there were many missing cases and exceptions.
WSL2 instead uses that utility VM, with a couple of special Microsoft kernel drivers to interact with the host system.
