 - Modules architecture should be upwards from `effectors` (modules that persist data and WASI modules) that will work with local binaries, local storage and syscalls to `pure modules` that perform business logic.
 - Splitting app to small FCE modules are easier to support, reuse and distribute
 - Each module for its own task (npm like)
