I understand that, but the resonant winding is not visible to users. Ferroresonant xformers appear to be two-winding devices for all practical purposes.
Yes, this is a practical solution in many applications.
In fact, my first thought was to look if there is a hidden third resonant winding. But I found out that the inverter transformer is indeed a normal one, though it has two bobbins instead of one which is usually used to reduce the flux leakage.
