Research direction

Start by tracing how WSL reads /etc/wsl.cfg and $env:USERPROFILE/.wslconfig during boot, then inspect how the CIFS_ALLOW_INSECURE_LEGACY setting reaches the WSL kernel. Determine whether CIFS version 1 can be enabled globally or through a configuration option, and verify that a CIFS 1.0 mount works after boot.
