Sorry for the late reply, I got sucked in RL stuff…

Yes.

Guess I can do that too.
I personally think it's kind of pointless as of now, where mpich is
available everywhere and openmpi is available on all but m68k (not
considering powerpcspe that yesterday has been resurrected from ashes…)

Anyway, What about:

https://anonscm.debian.org/cgit/debian-science/packages/mpi-defaults.git/commit/?id=57d37c200258e7512733d7ee36aade8bf806ffea

?

I do think this is a bigger improvment than hardcoding this in a donzen
of packages, everyone with its own data source.
