that's not true. i use visual studio code and emacs, both on windows, to develop scheme that runs on wsl (since many schemes don't support windows). in visual studio, i use bash in the integrated terminal which takes care of running the binaries on wsl, and in emacs, i update my user init file to use "wsl.exe scheme" for the scheme application, where "scheme" is in my wsl path. launching a repl works just fine, and it's able to load files without issue.
what path translation are you talking about? if there's an actually a problem with something you've tried, then it is probably a problem with python and not the setup. as i said, i regularly do what i mentioned above with no issues. wsl can see both files local to it and on the windows system.
