I don't know how this refutes what I said. If one can claim lack of AVX in Atom is an engineering tradeoff, then lack of particular feature in an ARM core can probably be an engineering tradeoff too.

I don't know why you quote area of the A7 core. People use small ARM cores because cost and power is important, not because it gives them headroom to add features that they won't use.
