2. If not, set it up using git config --global user.email email@example.com
3. Make sure that the git commit email is configured in your GitHub account settings, see https://github.com/settings/emails

I would rather not add become to every action. There might someone using a privileged user which then always does an extra "become" for every task.
What's with become on the playbook level?

Most of the Collection is made specifically to do administrative work. I, currently, don't see any spot where we'd need to distinguish between run as root and do this as a normal user.

If you don't want to use become for your whole play(book), you can also resort to another way of calling a role.

- name: Play
  become: false
  hosts: all
  roles:
    - name: icinga.icinga.icinga2
      become: true
    - some_other_role_without_become
    - name: explicit_no_become
      become: false

Switching the "global" become and the role's become also works just fine.
