I'd say this post provides an excellent summary.

There are gliders where, to obtain improved performance, it is sometimes
helpful to fly uncoordinated. For example, to persuade my Open Cirrus
(1967 design, 17.7m span) to turn into a strong thermal, it's sometimes
most effective to yaw it towards the thermal enough to induce the
beginning of a wing drop - then catch it and continue into the turn.

In the (most excellent) video "A Fine Week of Soaring", George Moffat
says that the handling of some first generation glass ships was so poor
that you could initiate a turn substantially faster by first moving the
stick in the opposite direction. Once the adverse yaw (in the desired
direction)had kicked in, THEN you'd move the ailerons into the turn.
