Wrong version of cordova-ios

With the latest CLIs, doing:

cordova create test
cordova platforms add ios
cd test
cordova platforms

shows cordova-ios 3.9.2

However:

ionic start test
cd test
ionic platforms

shows cordova-ios 3.8.0

You can then update to 3.9.2 with:

ionic platforms update ios

or...

ionic platforms remove ios
ionic platforms add ios

also gives me 3.9.2

When auto-adding iOS, is there a reason the ionic CLI doesn't default to the latest version of cordova-ios?

Thanks
