Well, considering that Kinematics 3D ^[an academic subject, which should supposedly be your first introduction to a 3 dimensional coordinate system after the pre-introduction back in Kinematics 2D and pre-pre-introduction when learning the number line. i.e. If the academic curriculum was sensible] uses Z-up and the main reason for Y-up being the 2D monitor having been the primary target for graphics output (where X and Y would have been taken and mapped first, requiring Z to be added when converting the paradigm to 3D) back when these things were started and us, slowly transitioning to having the same application being usable with both - AR/VR tech and monitors^[which would mean that in some cases, the user might be seeing some axes-gimbal, requiring a translation layer later anyway and in this case on the application developer's side, which makes it a cognitive load], we might as well all go with Z-up from the start.
