Rolf R. just reminded me off-list what the real reason is: MPI_STATUSES_IGNORE.

Yes, that makes sense.

Should this be an optional argument in that case, and eliminate MPI_STATUS_IGNORE and MPI_STATUSES_IGNORE, as was done for the C++ interface?

In my view, yes. I regret the demise of the C++ interface, as I found it cleaner, and this was one of those aspects. I am not disagreeing with Bill's points, of course - this is a value judgement. Regards, Nick Maclaren.
