not a problem if you don't cross them - my wsl2 disk image took more space than the windows install. I basically used windows as a web/email/chat client and a terminal to the real system, which was wsl2.
To each their own. I consider it great at what it does. It has limitations but what doesn’t? It’s a tool, use it, or don’t - I use it, it works for me.
I use the \\wsl$\ to get an occasional file out of wsl2 super easily, vscode remote wsl, the shared localhost interface and a wsl2 gui app every once in a blue moon. Don't think it's nothing.
What I don't use: files on the windows fs from wsl2 for continuously or vice versa.
