My primary gripe with YAML is white space sensitivity, it makes editing it in a hurry in a CLI environment needlessly user unfriendly. Virtually any other option is better for the person who actually has to modify these configurations later. If your configuration is expected to be hand modified directly by a user, it shouldn't use YAML.
