It just doesn't do anything.

Title. I don't know how to debug this so I really can't tell why or how it doesn't work, but that's just it. I've tried both nix-auto-follow in https://github.com/vic/flake-file and as a standalone tool, and both aren't doing anything. The flake.lock is getting overwritten because the date on the file does change, but that's it. Exact same file. I ran a diff by outputting the pruned flake.lock in another file, and they're the exact same. In contrast, https://github.com/spikespaz/allfollow does work.
