Let me paste the code for doing our own caching for you:
cordova_npm: function lazy_load_npm(platform) {
if (!(platform in platforms)) {
return Q.reject(new Error('Cordova library "' + platform + '"
not recognized.'));
}
var pkg = 'cordova-' + platform + '@' + platforms[platform].version;
return Q.nfcall( npm.load, {cache: path.join(util.libDirectory,
'npm_cache') })
.then(function() {
return Q.ninvoke(npm.commands, 'cache', ['add', pkg]);
}).then(function(info) {
var pkgDir = path.resolve(npm.cache, info.name, info.version,
'package');
return pkgDir;
});
},
There's really no "amount of code" argument here.

Bundling platforms with CLI would be like bundling all of the plugins with
CLI, or like bundling every npm module with npm.
Devs need to be able to try out platforms at different versions. We should
not do anything that keeps users clinging to old versions of CLI (e.g. they
do this now because they don't want to update to new platforms)
