Is the WSL documentation up-to-date?

I was looking at https://www.vagrantup.com/docs/other/wsl.html and read the part about Docker:

The docker daemon cannot be run inside the Windows Subsystem for Linux. However, the daemon can be run on Windows and accessed by Vagrant while running in the WSL. Once docker is installed and running on Windows, export the following environment variable to give Vagrant access:

vagrant@vagrant-10:/mnt/c/Users/vagrant$ export DOCKER_HOST=tcp://127.0.0.1:2375

Is this current in light of WSL 2 and the Docker integration that is available in the latest Docker Desktop version where the Docker daemon does run under WSL. What about other WSL-specific points on that page? Does anything need updating to address recent changes?

TIA for any clarification
