Is it accurate to call this WSL3? WSL 2 was released in 2019, but WSL 2.0.0 was released in 2023 https://github.com/microsoft/WSL/releases/tag/2.0.0

No I think it's more accurate to call it WSL Containers, or WSLc, but the release is indeed WSL 3.0.*.

It happens to be the major version reported by `wsl --version` on my system.

    NRR-WT1; wsl --version
    WSL version: 3.0.1.0
    Kernel version: 6.18.40.1-1
    WSLg version: 1.0.79
    MSRDC version: 1.2.7214
    Direct3D version: 1.611.1-81528511
    DXCore version: 10.0.26100.1-240331-1435.ge-release
    Windows version: 10.0.26300.9457
    NRR-WT1;

That is quite relevant, and compose ability is on the way, or for some workloads Aspire would be an alternative I guess.

Unfortunately most companies are too cheap to pay for Docker Desktop, and having Windows containers depend on a third party tool has been a problem in such customers.

Because using Rancher Desktop or Podman isn't also a given, due to similar issues.

Dockefile is still a thing.

And?

great to hear it thanks. I stumbled upon it on that HN article on containers, and since I’ve run doing other WSL benchmarks lately (testing kernel mitigations , which have a huge performance impact on the guest container), I re-ran those benchmarks on the upgrade.
