I feel like they don't advertise this enough. I was under the impression that it's a one way street from wsl1 to wsl2. Since wsl2 is not strictly better than wsl1, it's nice to be able to convert and pick the trade-offs you want.

Yeah, the mistake of using numbers instead of names gives the impression that 2 is strictly better than 1 and that migrations are unidirectional upgrades.

Even just letters like WSL-A and WSL-B might have given a better impression.

Will do! Thank-you.
