[mpiwg-hybridpm] mpi_memory_kinds default clarification (feedback window closing soon)

[Rohit Zambre]

Hello hybrid WG,

Thank you for the discussion at the MPI Forum meeting today. Summary points from the online discussion below.
The feedback window is closing soon as we are aiming to bring this into the January 8, 2025 Forum voting meeting as an erratum vote.
Please provide your feedback on the PR — https://urldefense.us/v3/__https://github.com/mpi-forum/mpi-standard/pull/986__;!!G_uCfscf7eWS!afD3t6uy6149GV5yiDaQgO42KiyIkf0ItDy_uTZAjmnNuPOC4c6QuJQI5XFHuUIKvqQpxQLUMWiquK3PoE2QmVh4Qe3O5pQ$ 


  1.  Strong agreement on an explicit clarification about the MPI library returning `mpi` and `system` at minimum when defaulted.
  2.  Some agreement and some ambivalence on including the additional statement “Different sessions may return different default values”.
     *   No strong opposition on removing the statement.

Based on the online and offline feedback, I have revised the clarification text to include the additional statement:
“
When defaulted, the value returned must, at minimum, contain the kinds specified in “default" and may contain
additional implementation-defined kinds. Different sessions may return different default values.
"

The additional statement clarifies applicability to existing MPI implementations with non-standard ways of choosing memory kinds.

Thank you,
Rohit
