You can't make a determination of connector dimensions based on device specs, because they're not strongly correlated.

The simplest explanation is that Lightning came out before USB-C did, and Apple did not want to risk another PR backlash from getting everyone to move to it after they'd just switched from the 30-pin connector cable.
