[OpenFOAM.com] OpenFOAM with Open MPI 5+

Open MPI dropped C++ bindings from Version 5, but some OpenFOAM components require these; is there any chance OpenFOAM will adapt, so that it could benefit from Open MPI enhancements?

This is truly curious. To my knowledge there are absolutely no OpenFOAM components using C++ bindings for MPI. Everything is wrapped in an opaque layer (UPstream/Pstream) or in an opaque handle (UPstream::Request), each of which uses the C bindings.
Which components have you found??
