There are way, way, way more uses of programming than simple CRUD services. Operating systems, game engines and browsers are only 3 examples where that doesn't apply, at all :) Besides, what's to say there wont be overlap in these newly separated services that will generate work in double because teams dont talk to each other? Or maybe you'll generate two average solutions instead of a better unified one. Even with multiple teams working on different aspects of a project, you still need yet another team to maintain the global vision of the thing. To make sure everything is consistent, to avoid work duplication, to consolidate solutions and abstractions and whatnot. Its fair to say the larger a development team is, the harder it will be to manage. Its even more true with large teams of average developers, which really is the norm when you think of it. At the end of the day, communication is key.
