But if you're a large team on a large project logic sparsity (with appropriate decoupling!) makes sense because then multiple people can change the code simultaneously without stepping on each others' toes. People can specialise where appropriate without having to understand the whole thing. The "sparsity" approach is obviously what enterprises see as good news mostly because it means they can have large teams without silos but in real terms it costs a lot of money to operate this way. Although I think as you rightly point out, Java has in recent years realised that it possibly went a bit too far in that direction historically.
