Dear MPI forum members,

I have made some minor changes to the proposal mentioned below, after 
the 2 week deadline (adding entries to the index and minor changes to 
the wording, no essential changes). I would be grateful if this update 
was considered for the reading, replacing the old document. The updated 
PDF can be found at 
the PR has been updated accordingly and the issue has been updated to 
reference the new PDF version.

Best regards,
Joseph Schuchart
