"WSL is a supplemental feature that runs a Linux image in a near-native environment on Windows, allowing for functionality like command line tools from Linux without the over-head of a virtual machine."
But since WSL 2 it does use a VM. According to wikipedia:
"a real Linux kernel,[4] through a subset of Hyper-V features.""with a Linux kernel running in a lightweight virtual machine environment."
edit: unless they mean user overhead of getting it to work. I kind of read it as performance overhead.
That would be great, but it would be gamed so badly.
Like those lists of "over 500 scientists have signed a document saying 5G is harmful to health so it must be true". When actually half of the people on the list aren't real people and the rest of them are political scientologists, dentists and people who know absolutely nothing about radio waves.
