I think this initiative already exists ... something which merges the
approach of cuda and opencl but I have no idea on the momentum behind

yes. Matlab has such support and the performances gain are in the order
of 2x vs 10x when addressing the GPU directly. All the time is spent in
sending data back & forth. Numba is indeed a good candidate bu limited
to the PTX assembly (i.e. cuda, hence nvidia hardware)
