 This project was started at the time when WSL2 did not exist and Microsoft just implemented AF_UNIX socket support. Today is is useful only when WSL1 is being required - which is really rare. Sharing Windows side ssh-agent with WSL2 does not need `wsl-ssh-agent.exe` at all! Please, read on next section on how to setup WSL2 and only continue after that only if you really working with WSL1.
