Pretty much this. I've owned entire applications and it's really fun when you're working alone. But adding a new developer that does not grok hooks (mostly because they are more use to imperative patterns than functional ones), and you will have bugs to deal with almost every single day. In a project, I was using Firebase as the backend and hooks allowed me to nicely abstract it away and use a language closer to business domain (like `useEntity(entityId)` and `useCreateEntity(entityData)`). Everything was more modular from changing the backend layer to breaking up bigger components.
