This is very nice. Like WSL on Windows 10, it lets you run unmodified Linux binaries, and uses the built-in macOS hypervisor to do so.
It’s not as useful as WSL on Windows (given that most of what I run also has native macOS ports), but might be a good way to do cross-compilation for exotic stuff that require Linux-only tools.
Incidentally, the reverse (running Darwin binaries on Linux) is still a work in progress, but it can apparently run part of the Xcode toolchain already, which might be useful for automated CI/CD pipelines.
