Don't you want determinism and deterministic simultations? If you do, you'll also need stub implementations (mocks, dummies) for your interfaces.
Some notes on that: https://blog.7mind.io/constructive-test-taxonomy.html

Most likely it won't if you organise properly. For example, if each your component is an OSGi module.

You can say the exact same thing about C-headers though.
I'm a proponent of keeping things in a monolith as long as possible. Break code into files. Organize files into modules. A time may come when you need to separate out services. Often, people break things out too early, and don't spend enough effort on thinking how to break things up or on the interfaces.
