Well, actually it looks like (IMHO) there are too many abstractions levels, in fact - I omit many of them on the scheme, and it's still complex. But if we think why that happened, it's because of multiple platforms supports mostly (native, server rendering, etc), each "sensitive for platform" part of logic requires at least module with interfaces, modules with implementation per each platform, module-injector for exact implementation and so on..
