At present there is no point, no. But that's because "trash" in this game is literally trash. Give things to actually focus down, atop some bits and pieces of utility (i.e., still output bonuses, but less obviously so / in manners impossible to estimate without their context) and there'd be reason enough to have AoE/overall vs. ST/focus damage on rare occasion in kits.
So while I'd agree, I'd say that points to a still larger problem than button waste that would be further cemented if QoLed around instead of being addressed: virtually all combat with 3+ simultaneously attackable targets in this game is creatively bankrupt.
