We didn't have time for Cupcake, but we definitely want to have some very well-defined limits in a future release. There is no nice error because what actually is happening is the app is running out of stack space -- some optimizations and new features in the view hierarchy caused certain functions to use a little more stack, which can result in apps that were skirting the edge of the stack to go over the limit.
We apologize, and definitely aren't happy about this; we had some some additional optimization of the code to reduce stack usage at the very last minute but found a little later that it still wasn't enough. Anyway, if this makes cupcake not a good as 1.1 to you, well okay, I guess don't run cupcake or something. (Btw, in practice, an application with a deep hierarchy like this is also going to have noticeable performance issues because of the work required to manage it, so this can be considered a nice opportunity to do a bit of good optimization.)
