If what you say is true about immunocompromised people I fail to see a public health argument against their quarantine and certification via passports. We already restrict a much larger and healthier subpopulation (the unvaccinated) so restricting this smaller and disproportionately more dangerous one does seem quite obvious to me, based on public health. And as you say, these people are most likely already hospitalized so quarantine procedures should be fairly easy to implement and follow.
