We already do. I think most people in this discussion aren't realizing that the current sysV init system is an extremely small pid 1 /sbin/init, and most of the logic in external rc scripts. Moving rc scripts to systemd declarative syntax is fine.

The important part with respect to software architecture is less complexity in pid 1. Subprocesses of init can be safely updated and restarted. More code in init is a real problem -- that's why systemd as pid 1 is controversial.

At the same time, there is a point to be made for having things in a single process - this makes it much easier to ensure that the crucial parts of the init system are available and working.

Can you elaborate? I don't understand this perspective.
