The complexity or size of the systemd code is not the issue, it is how 
it will be maintained going forward.  Especially since these are all 
system daemons, you know that there will be security bug fixes.  The 
current situation means every daemon will have to be rebuilt and 
redistributed to fix a bug in the systemd code.  It also creates inertia 
to fixing problems, thus inviting the individual snippets in each daemon 
to become hacked up and out of date.

The least you could do is provide both the raw source files and a 
library implementation, and let daemon maintainers choose which they 
prefer.  The best solution would provide a clean versioned C language 
API via a shared library

Do you have some picture of systemd adoption outside of Fedora?
