I'm always more interested in the 'less is more' strategy, taking things away from the already hyper-complicated stack, reviewing first principles and simplifying for the same effectiveness. This is ever more rare.
Yearly front-end rewrites are quite the joke, but they also reveal that the team didn't really get the underlying assumptions correctly.
Or maybe they just really wanted to try Redux/Zustand/Jotai/the cool new router and ended up making a mess that will need cleaning next year.
