cordova add ios creates xcodeproj in platforms instead of top level directory

What happens:
cordova add ios creates the xcodeproj in platforms/ios.
cordova build ios will overwrite any changes made in platforms/ios

What should happen:
cordova add ios should create the xcodeproj in the top level folder

Rationale:
With the current setup it is dangerous to use the xcodeproj. Any changes made e.g. to www/index.html will be overwritten by cordova build ios with whatever is in the top-level www/index.html.

Workaround:
In xcode, open the platforms/ios/...xcodeproj
Remove the www folder (only the reference)
Add the project/www as a reference
