I am not very familiar with these features. What system mechanism do you
currently use for this? Linux cgroups? Any concrete example of what you
would like to do?

OMPI uses hwloc for processor and memory affinity, so this seems a likely place to add the required support. Jeff tells me that it doesn't yet exist in hwloc - I'm wondering if you would welcome and/or be willing to consider contributions from our engineers towards adding this capability?
