When you apply `builtins.toString` to a path value representing a path in the Nix store (as is the case with flake inputs), historically you got a string without context (e.g. `/nix/store/...-source`). This is broken, since it allows you to pass a store path to a derivation/toFile without a proper store reference. This is especially a problem with lazy trees, since the store path is a virtual path that doesn't exist and can be different every time. For backwards compatibility, and to warn users about this unsafe use of `toString`, we now keep track of such strings as a special type of context.
