I think that the later is better for the YAML but I would rename it to `inhibit_warnings`

```YAML
---
target_definitions:
- name: Pods
  link_with_first_target: true
  inhibit_warnings:
    all_pods: true
    names: 'AFNetworking'
  dependencies:
  - ASIHTTPRequest
  - JSONKit:
    - '> 1.0'
generate_bridge_support: true
set_arc_compatibility_flag: true
```

What do you think?
