I've added isolation mode for the express and specific purpose of being able to basically jail spring in one dir. Querying any global file for additional path has absolutely no business for that. Querying ~/.springrc would mean I cannot have multiple, each with their own seperate data, installations somewhere in my userspace. This is what we'll need with for example desura. Querying the env var for additional isolation dir just means that my launchers scripts would plainly set that to empty.
