True, the dummy boilerplate is small, but it has to precede every playbook. (I also thought it had to include at least one task to be in effect.)
The main issue is performance. I'm not dynamically provisioning, so these things never change. I thought maybe there's some trick people are using to avoid the lookup, e.g. automatically using DNS/hosts file or auto-generating config files.
