Shaz took care of a lot of these for iOS (awesome!). Right now they live in the project template (along with the older scripts).
There is a current issue about the fact that these scripts are not updated when upgrading your version of Cordova ( https://issues.apache.org/jira/browse/CB-2448) Since the main consumer of these APIs will be CLI, how about we take them out of the project template, and instead have them live within the device repos. E.g. for iOS, have them live as a sibling of CordovaLib, and have CLI know how to invoke them.
