It may be disputed if the use of the rudder for picking
up a dropping wing near stall may be or not called a
coordinated action. What I was taught and am going to
teach is that proper coordination is highly dependant
on speed (AOA if fact), slower flight implies more rudder
for the same aileron action. At the stage where the aileron
loose their efficiency or even begin to exhibit
the reversal symptom, you are reaching the limting
case where proper coordination implies action on the
rudder only.

A side light on this and confirmation of your limiting case: last
winter we had a talk at the club from Andy Sephton, who is chief pilot
at The Shuttleworth Collection. A major part of his talk was on flying
the 1911 Bleriot. He said that on take off the Bleriot, with its
highly cambered curved plate wing, has so much adverse yaw plus
aileron reversal that *any* use of ailerons to level the wings on
take-off will cause a ground loop. The only way they found to manage a
take-off was to keep the stick laterally centered and to do all
yaw/roll correction with the rudder. BTW, both main wheels and the
tail wheel are on castoring suspension. He seemed to think this didn't
make things any easier.
