Doesn't go far enough for file servers

You just need to know parent directory's ACL and file's ACL. No need for anything more significant.
As I pointed out, for Windows ACLs, that is not true: you need to know the mv history of the file and (since files might have been moved out of and then back into directories with inherited ACLs) the ACL history of all directories it has moved into over its lifetime as well. None of this information is recorded anywhere.
