> What you're not understanding is that when we describe something as "monolithic" (or "modular") we're talking about if the design[2], not the number of binaries it happens to compile into. This is about minimizing complexity, and the way to do that is to break the problem into small pieces, while clearly and rigorously defining the interconnections between those pieces (an area that necessarily involves higher complexity).

Designs don't run under PID 1, or any other PIDs. Binaries do. You can't both complain about how insecure systemd is because it has a lot of code under PID 1, and then claim that the size of the code actually running under PID 1 is irrelevant.
