Agreed on most, and naming is terrible. Note that at run-time Python is out-of-the loop, since Newton Physics records a CUDA graph, and executes it, so performance is not impacted (aside from startup JIT time for modified kernels). I'd prefer C/C++ as well, and although you can call Warp-compiled kernels from C++ (without Python, see my https://github.com/erwincoumans/warp_cpp project), it would be better to have native C/C++ support without requiring a Python interpreter. It just happens that almost all Deep Learning/RL for robotics uses Python.
