I, too, like my systems to be booted up only a half way with half of the
services
being in an unknown/inconsistent state.

Well, you see the service it's waiting for. Then there are several things
which should help you when things go south:
1) If the service fails and it's crucial to the boot process, you'll end up
in the (apparently pretty despised by you) emergency shell, where you can
go through all necessary logs to see what went wrong
2) By adding a simple "debug" to the kernel command line, or making use of
systemd.log_level and systemd.log_target kernel cmdline options you can
dump the entire boot process logic to the console. You can't do this by
default, as it unnecessarily over-saturates the console line, which leads
to a significant slow down of the entire boot process. Also, as everything
is logged (as would any sane person expect), it would, again - unnecessarily,
bloat the system journal
You can't simply blame systemd that it refuses to boot when there's a service,
marked as the system administrator as crucial, yet which is apparently broken
in some way.

The main issue is not about people complaining (that's actually something we
want/need to), but in the version many of these users use. The systemd has
come a long way for the past few years, and there's been thousands of changes
to make things smooth and painless. But, of course, not all distributions
use the bleeding-edge version of systemd, which then introduces certain
problems:
1) An user complains about something which has been already fixed, yet not
backported to their distro
2) Some distributions (like RHEL) base their systemd package on a certain
version
(like 219 in RHEL 7) and then backport only some patches from the upstream.
Thus,
upstream developers shouldn't/can't be expected to know what mixture of
patches the
user uses.
In both cases, the downstream bug tracker is way to go. The downstream
maintainers
know their systemd package much better and can tell you, if it's an
downstream-only
issue, and a backport is necessary, or if it's indeed an upstream issue and they
can guide you here (or they'd do that on your behalf).

Honestly, I'm kind of impressed you stamp the "bad bad systemd" phrase all over
the place several times in your emails, yet you still expect people to be able
to (willingly) help you.

I know this might surprise you, but that's how systemd got where it is now. We
just need to filter out problems which have been already fixed, so we can focus
on solving the outstanding ones (instead of going through hundreds of bug
reports).
