While the idea is itself not without merit the problem is when people design these data oriented systems without abstractions and in fact it's often difficult to find good abstractions around the data the problem comes when the system, the data and functionality needs to change. There will be problems.

So while it's great to think about the data flow it's also important to think about the abstractions around it,.ie the (system) interfaces that let the system evolve without having to propagate changes everywhere while reaping the benefits of data orientation.

This is what ECS frameworks like Flecs can help with. They provide the tools and abstractions so you can write heavily modular code in this model. If you don't need the generic modularity, flecs will not feel like your gaining anything for the boilerplate you gotta write and the stuff you gotta learn, but if your making something huge that needs work for years, learning flecs is probably worth it.
