I integrated it in a top-100 app in the app store in less than a day and it works perfectly for us.
If you don't know the iOS or Android build chains I would imagine that its confusing and troublesome, but unless you are doing some fairly extensive native compatibility stuff you will reap great efficiency benefits from adding it to an existing app.
