No 3D touch is a very odd fragmentation. You'd think they'd want to shore up their devices to be completely compatible with this across the spectrum to motivate developers to use it as a key part of their UX.
Now when only X<80% of devices lack compatibility, I'm not likely to take the time to make 3D Touch a core interaction.
So your apps have to optionally use 3D Touch, Pencil, adaptive layout, fingerprint, and several other interactions that only cover fractions of their hardware line.
