Scrapping the Kylie doesn't mean leaving all the weapons it had on it go to waste.
Also, recent power armors have made advances in regard of their generator and capacitor systems. When we were in the field inhibiting our power generation, we were moving with minimal power because we were saving the energy we had left - we had energy left; possibly enough energy for one minute of continuous use from our aether weapons (if you refer to the teleportation unit, it seems the Mindy's capacitor batteries could store that much... which is the equivalent of the power stored in a aether saber-rifle battery - the M2 and M3 can probably store a bit more).
In a way, you contradictoed yourself. The weapon is indeed redundant: it's a weapon NIWS units can generate for themselves, but for us power armored pilots... it's not really necessary to have around or even desirable since our hardware is already better than this one.
Sure, the NIWS can make one, but it is a product pulled from thin air from the minds of mad machines. There has also not been a standard design for such a thing pitched. (I hate how that goes.) But no, the function of the aether gatling is not reduntant in comparsion to current systems, there is a severe lack of weapons intended for armor to armor engagement, or the engagement of large numbers of lightly armored combatants.
Yes, the aether beam saber is indeed formidable, and quite strong, but we have seen the most it does is punch a hole clear through the enemy armor, wounding the pilot. Then, after that shot, there is the time to wait for the weapon to build another charge (Thus Kotori's constant dual weilding of beam sabers). Meanwhile, we've seen the NIWS nearly cleave a Mindy in half from a distance, meanwhile, to get the same results from a beam saber, the pilot would have to close the gap between themselves, and their target (Not an easy or safe thing to do).
The Aether Gatling is simply meant to provide an alternative to the slow (but strong) beamsaber, and provide the pilot with the ability to engage other armors with increased capability to inflict large quantities of damage within a short time, but within reason. In truth, this weapon has been designed around the recent urge to tone down the level of technology in use. The Kylie forearm projectors and the beam sabers are indeed strong, but they're also overkill, the aether gatling would indeed inflict heavy damage on power armors (Thats it's job afterall), but it would also lack the heavy firepower that would be needed to cleave a hole through a gunship, which the forearm projectors and beam sabers are able to do (With the same ease that a NH-17 eats her rice balls.)
Either way, the aether gatling is intended to give all makes of armor increased armor to armor combat capability. It would serve as a useful upgrade for older armors, or a rather handy but reasonable boost in firepower to armors such as the Sylph, which is intended to fight inside of starships, where the collateral damage that would be caused by forearm projectors or beam sabers would be unwelcome.
