In all this talk about using a YAML subset, I'm surprised no one mentioned YAMLish:
https://pypi.python.org/pypi/yamlish It is a well defined subset of YAML and there are implementations in other programming languages. The problem with the 200+-lines-single-file library above is that it depends on PyYAML itself so, vendoring it will be challenging. Anyway, I think TOML 0.4.0 is good enough for our needs.
