Yep. And personally, I think it's a smarter model.

The directory system is independent (which is what gives us hard links). So the mechanism that works everywhere else - "traverse back up the file tree until you hit an ACL" - doesn't work in Posix.

The problem is that - in the standard Unix filesystem model - we have a flat root-level namespace. All files are uniquely identified by their i-node.
