I don't see any build where I'd have the spare flux to put energy weapons up front. Two plasma cannons is the only real build unless you've got the superhuman reflexes to juggle shield management, piloting, missile firing, and APL bursts, and once you've got those installed, build design becomes a question of what missiles will come in clutch, and what hullmods you can afford without touching your vents or eating too far into your capacitors.
It wouldn't hurt anything, sure, but I'm generally of the opinion that a mount that can't really be used for XYZ weapon type shouldn't just throw the option in. Watsonian reasoning is that versatility is expensive, and there's no reason to spend the extra money. Doylist reasoning is that having an option to do X when not doing X is always better feels like an oversight. That said, I'm not dead set on this, and if it'd be useful for the handful of dual autopulse gigachads, that's perfectly fine.
