This worked.
[..snip..]
tasks:
- debug: msg="The system {{ inventory_hostname }} will now be upgraded."
- debug: msg="The value of play_hosts is {{ play_hosts }}."
# This ensures that we dont proceed unless we're really only acting on a
single host, for sure!
# Another option would be to refactor this playbook to accept a
hostname/string as a target
# Another option would be to pass in --limit 'somehost' when running the
playbook
- assert: { that: "play_hosts | length == 1" }
# - debug: msg="The variable play_hosts is length of 1, which means that
only a single host will be upgraded at a time, proceeding with upgrade to
{{ inventory_hostname }}"

Thanks for the idea!
