When installing WSL you can still choose if you want to use WLS 1 or WSL 2, and you can switch between them. If you keep your files not in the WSL filesystem, WSL 1 is still the recommended choice because of the lower overhead for file access.

Plus WLS 1 is marginally easier to install because you don't have to enable Hyper-V

You also don't get "vmmem" process that eats memory and doesn't give it back

I recently updated my visual studio code development environment and it depends on WSL 2 now. It seems to be that this is the direction MS is heading.
