ACTUAL RESULTS

Ansible throws this warning:

[DEPRECATION WARNING]: The `ansible.module_utils.compat.selectors` module is deprecated. This feature will be removed in version 2.19. Deprecation warnings can be disabled by setting deprecation_warnings=False in ansible.cfg.

Thanks for spotting and reporting that!

The compat module was stripped down here: ansible/ansible@d2ba76c The reason is that ansible-core dropped Python 2.7 support. This collection still supports Python 2.7, so we'll likely have to vendor the old code to avoid triggering that deprecation warning.

Or alternatively only import that module util for Python < 3, since then it's clear that an ansible-core version is used that still fully supports the compat module.

#871 fixes this.
