What is the evidence for and against systemd?

Tht's exactly what I've been wondering this past month.  There must 
have been reasons for getting involved with systemd.  And replacing an 
antiquated init system is a plausible (but controversial) one, that 
the DDs seems to have taken some time ago.  systemd is available in 
wheezy, presumably as an alternate init.  Does anyone know whether it 
is installed there by default?  I don't have it installed, but then 
I've been upgrading since well before squeeze, which gives a different 
pattern of packages.

But then init started expanding.  Perhaps there are other facilities 
that are best handled in a coordinated way with init (though I don't 
see the specifics).  I'm all in favour of hardware memory protection 
and the like separating disparate system components as a step in the 
direction of safety, and I already deplore the monolithicity of the  
Linux kernel.  (Perhaps formal verification would be an adequate 
substitute, but we're not there yet.)  But with adequate code review 
and such we manage to get along.  I'd like to hope that systemd gets 
that kind of scrutiny if it's going to become integral to deployed 
Linux distributions.  The rumour mill implies that this isn't 
happening.  But I have seen no real evidence either way.

And making systemd an essential dependency of important system 
components that at first sight have nothing to do with it seems, well, 
unfortunate to say the least.  And the success of the funtoo 
distribution at providing gnome without systemd suggests that it is 
quite unnecessary.

I'd really like to see some of the evidence.  Some of the rationale for 
choosing systemd, and, later, sticking with it.  Did it seem 
to be a good idea at the time, but later morphed into an execrescence?

I just don't know.

I'd like to.
