yum-version-lock should also be replaced here with {{ versionlock_plugin_package }}.

Should this then better be package to be more generic?

Better use ansible_distribution_major_version | int >= 8 or ansible_distribution_version is version('8', '>=') because for higher version numbers this comparison is not returning the expected result, e.g. '10' >= '8' evaluates to false.

ansible_os_family should not be required here because this file is only included in tasks/main.yml using ansible_os_family to derive the filename.

Agreed. I primarily didn't want to diverge too far from existing statements in e.g. Debian.yml which has the same unnecessary check. But I'll remove it here as it's been discussed (I'm leaving it in Debian.yml for now though as I haven't tested there)

Actually I've just removed all that and gone with ansible_facts.pkg_mgr to simplify things.

versionlock_plugin_package: "{% if ansible_os_family == 'RedHat' and ansible_distribution_major_version >= '8' %}python3-dnf-plugin-versionlock{% else %}yum-plugin-versionlock{% endif %}"
