It depends a lot on what you're hoping to do. There's a happy medium for a large app between "every component manages their own state/props and those of their children" and "every component is a stateless vessel for VueX data".

I think if you're at the point where "passing data around in props is a nightmare" that's the pain point that VueX is meant to resolve, and it should feed into the solution. But following the principle of "components should manage their state without VueX if it's easy/convenient for them to do so" is a good way to avoid the global state becoming too unwieldy.
