We only create symlink for tasks, not individual functions. The symlink is create right before the actual runfile is created, indeed we cannot create the symlink right after running the task since a failure or execption can happen, in which case the symlink wouldn't be created, and symlink are particularely useful when the task failed! Another option would be create the symlink after the runfile is created, and before the script is executed, but that means we need to duplicate the code in case of Shell vs Python task.
