The contents seems to be unaffected, but the modification takes place
anyway.  So, from a directory point of view, it is a modification.  I
think this behavior is correct.

Because a change took place.

Yes: you could add a layer (an overlay) that checks modifications before
they are dealt with by a database, and simply ignores those that are
already present.  In practice, you move downstream the check that should
have occurred at the client.  I think this overlay would be very simple
and could be of general use, given the number of relatively "dumb"
clients 'round.
