Does Mojo support Parent/Child Grids (nested kernels)?

I’m looking for an equivalent of:

__global__ void nestedHelloWorld(int const iSize, int iDepth) {
    int tid = threadIdx.x;
    printf("Recursion=%d :Hello World from thread %d block %d\n",
        iDepth, tid,blockIdx.x);
    if (iSize == 1) return;
    // Decrease the number of threads by the power of 2 (rshift)
    int nthreads = iSize >> 1;
    if (tid == 0 && nthreads > 0 ) {
        // Dynamic parallelism - requires -rdc=true for nvcc compilation
        // clangd doesn't support CUDA dynamic parallelism checking
        nestedHelloWorld<<<1, nthreads>>>(nthreads, ++iDepth); // clangd-ignore
        printf("--------> nested execution depth: %d\n",iDepth);
    }
}

Its unclear to me whether mojo supports directly via the gpu module or if this is only possible via jumping to max..
