Its big and bloaty and its a good thing to have more than one implementation?

ugh... what a mess...

Its a good thing nobody invented a boot system that depends on things
that was designed for desktop and not boot systems, things like
DBUS... oh wait...

Btw, the article claims: "There is no way to reliably bring up a
modern system with an empty /usr. "

Sure its possible. The process is traditionally called bootstrapping
and is not a new problem[1].

1. bring up the disk devices
2. mount /usr
3. bring up the rest of the system

Make sure that everything needed for step #1 is available in /
