Probably not, people in this situation tend to lie to themselves. Apple still thinks they are Apple and that their stuff don't stink, no matter how much their products lack features and performance. Why does the 5SE not have 3D, why does it not have the best front camera? Its thicker, so why not have 2 days battery life? Why? Because they thought they could get by with less, that is an Accountant thinking, not a leader.
Because they wanted it to sell for $250 less than the 6S.
If it had all the features of the 6S, I don't think they could have done that. As it is, the sacrifices you give up for the SE are pretty small considering the cost.
It's interesting that on the one hand the 6S is a bit meh because 3D Touch isn't all that, but on the other it's such a big omission from the SE.
