If you’re inferring petsc user base through brew packages, I would argue that these aren’t really all that representative save from direct dependency download. So mumps etc likely wouldn’t correlate well since its not listed as a direct dependency for the petsc package. Theres also the question of whether the counters on the dependencies are even useful to begin with. I suspect it’s probably more common that users clone petsc and then use a combination of package-manager packages and —with-download configure options.
