The only valid argument I see is monoculture. If systemd every does fall out of favour, become broken or compromised in some disastrous way it will be a lot of work getting going again.
Anyway, I’m not sure I see how a non-gigantic, slow-moving, pretty-much-finished open-source project like systemd can become broken or compromised in a way that forking it cannot solve. This isn’t Chromium we’re talking about, where it takes an army of world-class developers just to keep it from falling so far behind as to be basically unusable. If systemd were to stop being developed in any way other than security and critical bug fixes, it would still remain useful for many years.

The same is true of Linux itself.
