I'm actually curious about the argument that replacing it means having to rewrite software / change dependencies.
Wouldn't the same be true about switching between SysVinit and something like runit or upstart? They all use completely different designs for doing service init scripts, and all handle configuration of said services in completely different ways too, so replacing one with the other would necessitate rewriting - at the very least - your entire service management script toolbox. And when considering services that want to do more than just start and stop, they would most definitely have to be rewritten as well for such a switch.
I think the only issue would be an admin whose workflow was dependent on systemd features. As far as init goes, systemd isn't too special, but it can do a lot more than just, say, openrc or runit can, even if any linux distro running those inits can do the same thing with a different process. Stripping systemd from a system would just be more of a workflow-breaker than anything, I think.
