The bulk of the modules essentially generate Python payloads for Ansible to ship/run/track. Most of the burden is on the controller. Not all.

Ran into this recently with Ansible 2.17 which can no longer fully run (dnf/yum modules don't work) on EL8 targets due to platform-python being 3.6.
2.16 still works but goes EOL in May, when the OS is supported until 2029.

More of an own-goal than anything. This'll just push more to Shuttleworth.
