As a kogmaw main, this is a very reasonable addition to a build, providing more overally damage from his kit including his W. I find it dependant on the situation however. If your team lacks in magic damage or poke, this will provide such a significant more amount of damage even more so if the enemy team is squishy. The penetration easily makes up for the loss in attack speed in the long run being a "ranged adc" you can cripple your opponent from afar without being punished.

The only downfall of this seem to be when the enemy mayt have enough sustain and magic resist to handle Koggy's ults. A Sona with aegis will negated alot of your pokedamage late game reducing the potency of the penetration. When this seems to be the case, attack speed will be better allowing you to take advantage of his high amount of mixed damage. Attack speed will also moderately increase your magic damage with auto attacks, which is already understood by kogmaw players.

Overall it seems to be a situational buy, its can work well in almost all cases and provides you with a better laning phase because of kogmaw's highbase damage.
