You can still do it, you just have to tweak your calibration parameters to accept a different focal length for the second camera. It's a huge pain but doable.

Maybe it will be another software update, or something 'software new' for the iPhone 7S or 8 like they did with live photos & the 6S.

Can the perspective difference be fixed in post? It's not going to be pretty interpolating the pixels using the other lens's data.

I think you are thinking about more traditional Lightfield cameras - this doesn't appear to be that.

It definitely won't be pretty, but whomever puts the work in will probably benefit from it somehow.
