I am not a PDE person, but my intuition is that those sparse matvec
solvers often run in conjunction with AMR or FEM where static,
one-time initialization is impossible.  However, I'll trust the PETSc
team and similar-minded folks to figure out those issues when they

Perhaps the LLNL folks know something about the multi-physics codes
which solve continuum equations using FEM and can confirm or deny the
possible utility of RMI in those codes at exascale.
