Is MPS Volta discontinued

Reference:
I was reading version vR410 of MPS till mid march and suddenly in the next revision (vR418) all the Volta references in the document have been removed, including the one mentioning that MPS Volta isolates address spaces of all the MPS client applications as well as CUDA_MPS_ACTIVE_THREAD_PERCENTAGE.

Questions

  1. Why MPS Volta version has been removed from the docs and development? Although volta architecture white paper mentions it
  2. Is MPS Volta discontinued? If I am using cuda 10.1 on RTX/Volta GPUs then which version of MPS am I using pre-Volta or Post volta?
  3. When can an improved version of MPS with be expected?
