Nope. Electric action and electro-pneumatic wind chests (with membranes) were then a commonplace in France, Germany, ... The US rather quickly moved to individual electromagnetic valves (one per pipe), requiring more wiring, electricity, etc., but that was a "rich" solution.
The "back to full mechanical" was a reaction against that, therefore appearing in the late twenties (Orgelbewegung in Germany) although the tonal scheme was the first aim. Mass-producted mechanical action appeared after 2nd WW.
Reims cathedral was the first case, in France, of a newly built (1938) mechanical action for a very big organ (4 manuals and pedals, about 85 stops), and quite a bit experimental because the skills and know-how had somehow to be "restored"...
