Hey ng12, author here. I totally agree with you. I am the biggest proponents of keeping things simple. I initially was hesitant to introduce Vuex. I've written a few huge apps in Vue without anything else but Vue. The cool thing is you can, of course, continue to do that. But again, you just have to follow some strict patterns. Or, to make it simpler, you can get some help from Vuex and let it help you follow those strict patterns. Either way, one is best off if they follow a strict pattern. If not self guided, then library guided. Especially on a big team you can reduce the stress of that strictness if everyone uses Vuex. With so much code flying through GitLab, Vuex is the answer, for quicker code reviews.
