Ah yes, now that you mention it, I think FG said to use that as a temporary solution until it's been implemented. Though, don't replace the config file, just add a launch option instead.

For Steam, that would be on the properties of the game > Set launch options.
For retail, you can use a .bat file to launch the SOMA.exe file with arguments.

The argument should be the relative path to the new config:
mods/modname/config/main_init.cfg - Or similar
