The further effect of rudder is ????????????

My point was to emphasise that whether a glider can be ruddered round or
not depends on the airframe, not to continue the discussion about the
right way to turn a glider.

Libelles, which have noticeable dihedral, can be gently steered with
rudder alone while a nearly flat wing, such as a Junior, will tend to fly
sideways rather than turn.

I think this is useful stuff to know for the same reason that its nice to
know that you can fly gentle aileron-only turns in, say, an ASK-21. If
you lose control over one axis for some reason, then knowing how to
compensate may just save your life. However it would surprise me if all
gliders react the same to uncoordinated turns, so trying aileron-only and
rudder-only turns at a safe height could be a worthwhile exercise for any
owner.
