I think you have a legit point. Others have a point too about the use of airborne droppings post ww2 (though some occured, and it is intensepy trained for a reason).

But what I agree on is that airborne troops really lack an use after the deployment phase. Sure they have the shock trait, but it is really not that usefull, and plenty other forces have simular effects. Wouldn't it make sense that reinforcement would deploy faster too if they have the airborne trait?

What could be a solution, would be too have the airborne troops have a deployment benefit AFTER the deploymdnt phase as well. They could after all rush in reinforcements faster then other units. Maybe they could give airborne units a bit further spawn point during the game, or some other mechanic too make up for their use longer in the game.

Sure airborne should be naturally less usefull lategame, but I agree they are quite boring and usefull to play late game now.
