What was gained was that the filesystem auditing code will have logged
the fact that you (as identified by your LUID, which will still
indicate *you*) made that modification. That's the whole point of
LUIDs: to provide a reliable user identity for auditing changes to the
system.
Once again, LUIDs are not used for authentication or access control.
They are used for *secure auditing*.
