Hi all, I would appreciate if we could re-visit the comments on the Session friendly spawn proposal [1] from the plenary discussion at the last MPI Forum meeting in March. It would be good to discuss how we should move forward with this, i.e., anything to revise/ prepare for the June 2026 MPI Forum meeting?
