> RPM doesn't know about modules
yes, dnf is the component handling modules and you can express dependencies among modules

> so we can't get a nice "Requires @container-tools:2.0/podman" or anything close to it.

this could be expressed if tripleoclient were built as a module and have in its modulemd:
  dependencies:
  - buildrequires:
      platform: [el8]
    requires:
      platform: [el8]
      container-tools: [2.0]

Not suggesting to do that, just for completeness of options :)
