Not quite, you can position yourself to control what you hit to a certain extent. Precise control over what your hit is harder to achieve as the number of enemies goes up or as they crowd closer together, but this is why there is a separate single target "copy" spell like Holy Spirit.

Making it a target on enemy aoe only further promotes controlling what you're attacking and allows for more niche uses.
Target based AoE comes with downsides too. You can't precast, and worse for PLD you can't center the AoE on the center of a collective group of enemies. The centering problem can be painful on DPS like BLM that only have targeted AoE. If the tank hasn't arranged mobs close enough, or for whatever reason the mobs can't pack together tight enough because they are fixed in position or have large hitboxes, your AoE will miss some targets. Non target AoE gets around this by allowing the user to stand in the correct position to hit everything.

if things like overpower and orogeny or holy spirit and holy circle collapsed into one button with reduced damage after the first target it would lose out on nothing gameplay wise and just clean up bar space. I'm all for complex gameplay but choosing one or the other based soley on if its single target or aoe with no other class interaction isnt complexity, its just bloat.
I don't mind if you don't care for separate AoE and single target skills, but there is no way that making everything AoE won't cause problems. Those problems won't be evident everywhere, but they will pop up in some content. You'd have to avoid your Requiescat combo on tethering adds, or in situations where you can't afford to pull everything because of mechanics or special content like Deep Dungeons. It's not bloat. It's precision that lends itself to decision making and it provides complexity for the devs to build encounters around, if they choose to do so.
