This package does not support Python 3.12. Please test it with Python 3.12 as a matter of urgency as the default will change in early June, as per message on gentoo-dev: https://www.mail-archive.com/gentoo-dev@lists.gentoo.org/msg99104.html. Please check the information provided in the tracker. Ask in #gentoo-python on IRC if need any help.
The package does indeed have 3.12 compat, your scan may have just misfired since not all versions in tree have a clean bill of PythonCompatUpdate health? But I'm particular the issue is the live ebuild, which hasn't been synced. I rather question how much a live ebuild matters here. :D
