No, the benefit of airborne units is that they can deploy behind enemy lines. The intent is not to allow players to instantly place units anywhere on the field but to allow players to sneakily insert units at the flanks. There is also the benefit of surprise in that while there is a delay from the player clicking to them dropping, from the enemy's perspective it is a sudden appearance of troops.
Why should it be such an explicit tradeoff? Airborne units are expensive and doctrine based. They had to have long delays because Airborne's ability to keep the pressure on was unbeatable, especially when stacked with doctrine abilities that benefitted only airborne. But now air-dropped units are limited by the supply system. Do the same problems even still apply?
I've always been a bit of an airborne partisan, but at this point its very difficult to justify a drop behind enemy lines. The risk compared to the benefit is often too great, especially with elite units like commandos and FSJ. Delay is the major factor in that. And when you drop them inside your lines its slower than calling them on normally. Even a small reduction (5s? 10s?) would go a long way.
