Perhaps Ives met severe resistance internally regarding this feature and the lack at least on iPad can be explained by internal politics? (The SE exception can be explained by cost cutting rationales.)
XR - I dunno.

The lack of 3D Touch on XR was due to cost, and apparently their plan to ditch it everywhere.
The lack of 3D Touch on iPhone Pro...that's disappointing. It would have been a great "Pro" feature to offer. A "Pro" feature that allows you to be more productive on your phone. Aside for the video features (which I don't see being used by professionals anyway), what makes this device a "Pro" anything?
