"Scalable" is probably the wrong word, but I assume there will be policy
virtual paperwork, and it means you have to persuade MPI maintainers to
support it before you do anything new, or you need to fork the MPI

Of course I'm happy with automation and generally having things just
work.  I was only meaning to use what I've done as an example.  It's the
general setup I don't like, but this doubtless isn't the place...
However, I do have problems even with Fortran packaging, given the
nightmare of module file incompatibilities and needing to use devtoolset
