I agree with Dick. We’re getting very strong ISV feedback that an MPI-3 compatibility break will constitute a serious adoption barrier for them.

I know there have been suggestions that binary compatibility could be expendable. I am not aware of any decision that it is "not a goal"

I remind you all that this survey did not use a good sampling technique. For example, I suspect most people who solve problems with a code that happens to be written in MPI want their code to just keep working and never saw the survey.

I don't believe that binary compatibility is a goal for MPI 3 and in
the survey users rated it quite low on their priority list.
