OP is the one making an assertion, so the burden of proof is on them.

That said... I suspect most the system-wide breakage that would have
been expected would be due to init scripts and systemd ameliorates that
to a large degree.

Inherent flaws in a setup doesn't mean that shit doesn't break. Ideally,
yes, there would be no flaws, but this is the real world.

Doubtless, we all try to strive towards perfection, but there is no such
thing in practice.

In practice, I agree that it probably won't break much, but your
arguments largely don't hold water.
