Escape where, OSX has similar thing which seems to be even less 
documented (only my impression might be wrong).
Solaris has moved something similar.  AIX has never been truly SYSV and 
needs special hardware. BSD's will work but
have their own set of fun and are geared in my experience more to people 
who like to mess with the code. And some
of them are planning to move to the thing used in OSX (or in it's 
opensource upstream). Windows also has extensive
ways to manage how processes will start in startup etc.


Maybe the thing is that world has moved forward and there is needs which 
traditional sysv init doesn't answer
anymore. And any way you feel about systemd something similar would have 
come anyway and it actually did and
people weren't happy so in came systemd instead. If there is real 
problems with systemd I am sure someone will sooner
or later fork it and do different version. That's the choice in 
free/open software it's freedom of making your own if the
current solution doesn't work for you. Nothing of this freedom is taken 
away.

It's just that those people who actually do work for getting the 
distributions out have seen that systemd is only
maintained solution at the moment. I think it's somehow telling that no 
one else is even trying to make better
solution to the problems. It doesn't mean there isn't ways to improve 
systemd (or make a replacement), it just means no one is willing to
do it.
