I don't think this is intentional to cut cost. I simply think that the chip was primarily made for devices with one port (iPhone, iPad) and this is a bit of an afterthought.
I wouldn't be surprised to see a future product with 2x USB 3.0 10 Gbps with DisplayPort support on the next generation, A19 Pro or A20 Pro maybe, if the product has enough success.
