Ansible has started loudly deprecating the "with_items" construct in favour of the new "loop" construct. The old one is slatede to be removed.
Woe be anyone who needs to run ansible-playbook on both old distros and new, and needs to have the same playbooks work on both.
At least it looks like a long deprecation period, but this kind of thing makes me wonder if I should look at some other tool instead.
It only needs testing of a few edge cases.
I'm too lazy to test it myself..
