In SLE-15-SP6 we have python311-CommonMark version 0.9.1 which should meet the requirement as long as python-rich is changed to build for Python 3.11, and it looks like that has already happened at: https://build.opensuse.org/package/show/devel:languages:python/python-rich And I see that python311-rich is already available in SLE-15-SP6 and SLE-15-SP7 via the Python3 module, so this no longer has anything to do with Backports anymore.
