I'll add to the docs for other commands. prepare actually does receive those extra args but it doesn't call any platform scripts, so there is nobody to pass them along to.
create doesn't call any platform scripts as well, the subsequent "platform add" does, but allowing extra args to "cordova platform" is not obvious. E.g. need to decide what exactly the following means: cordova platform add ios android -- --some-arg Anyway first we should find out if there is a need for this. If yes it can be figured out.
