Currently JS frontend folks also classify MVC as "problematic", yet a lot of successful software was written that way. So along with J2EE folks, this isn't really the community to look for style standards by default.
Honestly, given that I know of no two developers that have the same understanding of what MVC is and how the code should be divided, I have a feeling there's something wrong with the pattern itself, too.
I don't have a link handy, but I read a piece by one of the original MVC pioneers claiming that the pattern was designed for encapsulated components, usually fairly small, not entire applications. I suspect many of the quirks and disagreements between different MV* architectures derive from this fundamental misapplication of the pattern.
