To my experience, Cake simply does not grow beyond their own blog tutorial.

Maybe they fixed this, but last time I used Cake, for instance, if you were overriding hooks in the Model to e.g. change the data as returned to the view/controller, you had to do this different depending on how the data was collected. So in the same hook method of the BananaPeer, you either got a single Banana, or an array of Banana objects, or an array with a key "Bananas" which had an array of Banana objects. There was no way to figure this out except with a lot of testing. There was no uniform way to implement standard features and constraints inside the model.

Cake was full of this kind of shit. It was, simply, horribly badly designed and to my impression only popular because its web site was pretty. The source code was horribly undocumented and the internal SQL query building process was a disaster.
