I think for bigger projects you really have to think about what your UX is going to be. Sometimes you want UX and features so different for devices that looking to share code at all costs can result in a lot of useless code in the builds but if your project is going to use a similar UX I think this paradigm works. About the 90% of code inside the render functions, it made me think about the time where people were complaining about huge Angular controllers. I agree that render function can be large sometimes but I think that if 90% of code component is in the render function, you should probably move some code to the stores.
