You could process the hints using command-line options and not make a programmatic API at this time. If there is no good default, we can talk about whether the important MKL hints are really MKL-specific or something that other PETSc classes might be able to use. (There are uses cases for implicit conversion to ELL or a compressed representation.) But let's not make a programmatic hints API just yet.
