The one issue with this approach is that it would still traverse all hidden folders, which could be expensive (e.g. in a git repo with an enormous revision history in `.git/`). `-not -path ...` just prevents entities from being printed, not being traversed. To actually prevent traversal, you need to use `-prune`.
