We could probably be a bit smarter about not adding variants from
variants.conf when they conflict with what's already been requested, but
I don't know if it's as straightforward as it sounds. At present, if you
don't want +openmpi in this situation, you have to install with an
explicit -openmpi (which is then preserved when you upgrade).
