The driver change implements the new location of the module files. If landing only the driver change or only the module output location, the module files will not be found. I can try adding both locations to the search path, but I think it will cause more problems than it solves (`.mod` files contain the hash of the `.mod` files it depends on, and cause an error if the first match has a different hash)
