It's not that.  Those lines come from the original fuse acl support in
commit 60bcc88ad185 ("fuse: Add posix ACL support").

Maybe the thinking behind that was that the server might modify the
acl when setting it.  Not sure if this can actually happen for network
fs.

In any case it is unlikely to matter in real world cases.  For now
let's just document these quirks.

Thanks,
